Z-Sam, I'm not sure what kind of pattern you'd find crappies on there right now, but my 8 year old and I fished with some friends on their boat there in April, and if you get into what Pymy has to offer in terms of slab crappies, you'll never want to fish for crappies at Arthur again.  As others said, what's big for Arthur is a throwback at Pymy.  
 
Until this year, I had only ever fished for carp at the spillway at Pymy, save for a few half hearted efforts shore fishing in different spots.  We've made two trips with our friends on their boat this spring, and let me tell ya if I had a boat I'd probably never fish Arthur again unless I was after wipers.  And Arthur is 30 minutes from me, while Pymy is 1.5 hours.  

Went out Friday after work with for a few hours from 5 -10  and managed 13 eyes but only 3 were keepers, also found a couple nice slabs and perch. Nice to see a upcoming population, hoping for few more keepers this week. All but 1 were on a 1/16 jig and night crawler.

Yeah I sometimes get that same feeling.  After catching that pig crappie out of Wilhelm I really want to just fish there.  But I'm 15 from Arthur and an hour from Wilhelm.  My boat is fantastic but my trailer is total balls.  Big fish or not, I still enjoy Arthur.  Hate to break your heart, but Shenango wipers could eat Arthur wipers.  :)  The only grace for Arthur is endless channel cats.  In the perfect eating range for me and fun to catch.  With the kayak_tub I'm more likely to head up to some of these lakes which will probably just ruin me.  

 Sam, I enjoy your posts so don't take this the wrong way. "That pig crappie out of Wilhelm" is long but very skinny & under fed. The ones from Pymie are shaped like fat paper plates. Arthur does have lots of smaller Byrds which is great to see the stockings are working out. But have caught numerous 28"-29" very thick fat fish & some 30"-32" over the yrs.
 
 The Cats we catch are too big at arthur for eating, many 28" - 32" with a occasional 34"- 35". We don't keep the smaller ones any more but they were good eats.
 
 Arthur is still my favorite 'cause I could walk there & the memories.
 
Good Luck
 
 
 

Our last trip to pymie we brought home 6 between 13 to 15 inches long. Wont be hitting the lake again until next friday after we get back from vaca. Hopefully put some walleye and crappie in the freezer then!

Crappie - no offense taken.  That crappie was only 1.3lbs in fact.  Most of the white crappie I've caught are skinny regardless of the lake... just thought that's the way they grew.  There are clearly big crappies in Arthur, but they aren't where I'm fishing and/or I'm not fishing right.  Which is fine really.  I fish to have fun and relax, and "hard" fishing isn't what I'm interested in.  I want to soak bait and watch bobbers go down.  Won't catch me trolling, I don't care how effective it is.  And I'm not into throwing lures.  Give me a bucket of fatheads and I'm gtg.  
 
Arthur cats are one of my main targets.  The average cat I keep is probably 22", which is usually a 2-3lb cat.  Couple nice fillets after you trim them up.  We don't really tie into the big cats.  Only one north of 10lbs in the past 5 years I'd say and it went back.  I know they are in there, but again, not where we fish I guess.  
 
I think the 422 end of the lake probably isn't as good as your end.  But I've been fishing that side for so long it's like home.  And I don't have to put up with tournaments or full parking lots.  Or loudspeaker Jesus on Sundays.  And I know I'd be better off spending time on Pymie for better class of fish, but man it is hard to drive past an enjoyable lake so close to my house.  

Oh yeah forgot about those Shenango wipers. See lots of pics on social media of those hogs and you don't have to make a night long suicide run to get em consistently.

Guess one thing we can all agree on is that we've got some pretty good warm water fishing opportunities along the northern half of PA's I-79 corridor.

My boys and I have got the skunk on Arthur channel cats so far this year. We were on em pretty consistently the last two years catching a handful in the 10-12# range and plenty smaller but nothing in 3 or 4 trips targeting them so far this year.

agree 100 % on a lake so close to home. Live in Newcastle.. MYy goal is to learn Arthur , Beats drive to Andover.  

 Sam, I hear you on the relaxing/enjoying & passing by Arthur  Heck that's a couple more hrs. fishing time. You can pm me on a spot for your yak at Pymie you will enjoy & should be able to fill your freezer with Jumbos & Slabs.
 
Heading to camp up there now so will respond later.

Been catching them mostly on crawlers this year.  Bonus is that the wipers love crawlers AND you might luck into a wally.  Soaked some cut bait which is our normal standard but they haven't been interested.  They'll jump into your boat for an alewife though... that'd be my best advice for Arthur folks.  Get yourself a cast net and learn how/when to use it.  Tip: NOT IN 4" OF WATER AT THE **** LAUNCH!  You can see clouds of bait on the finder once you know what to look for.  If the schools are on top (when the water gets another 5 degrees warmer or so) they are very easy to find.  Another tip: heavier is better.  These are FAST.  Get a smaller net you can work reliably and pay extra for 1lb+ lead per foot.  The cheap nets will catch 'wives but you'll work a lot harder for them.  
 
If you're on the 422 side shoot me a PM and I'll give you some suggestions for cats.  If you are 528 side I'm not your guy.
