has anyone tried these waders/boots?

I like the Studded felt boots. I feel the studds give me better traction. Had a pair that were just felt and could tell the difference between the two.

You won't have any problems on the tribs with straight felt bottoms.
Studs would give a little better traction when crossing swift current.
I think studded aquastealth is the best boot for Erie if you do a lot of walking.  

have the cabelas GII waders they are very nice for the price mine wore kinda fast on the inside of the knees. this was because the didnt fit the best.  im to big and short.  also have the boots with out the studs the lasted for like 3 years,  and the waders are going on 4 with some leaks by the knees.  just got a new pair of the boots with out studds dont like the studded ones.

You might want to check out Reddington.  I have the Reddington CPS Breathables (http://www.fishusa.com/Redington-CPS-Stockingfoot-Chest-Waders_p.html?i=F9F7908E5B8243F395D90298EB68BDCE) and I absolutely love them.  They might be a little more than your price range, but well worth it.  You may want to take a look at Gander Mountain also.  I just saw they came out with a new style of 4-layer breathable waders for $99.  I had a pair of Gander Mountain waders before my Reddington's and really liked them.
 
As far as the boots, I'd agree with dano that studded aquastealth is the way to go.  I have Korkers Wetlands with interchangable soles, but come steelhead season the only soles I use are my studded aquastealth.  They offer tremendous traction & are great in the snow & ice. 

I use the Cabelas Premium Dry Plus waders. (the $129.95 tan ones)  I've had pretty good luck with mine.  I'm on my third year of my second pair.  The first lasted five years until a jager sliced a rip in the leg.  At first I had a problem with a leaky foot bed.  Sent a pair back still under warranty and received a new pair plus I got some great advice from one of Cabalas' wader experts.  He told me to be very careful when pulling them off, when wet, not to stretch the neoprene booties because this is often what causes a leak.
 
For boots I use Simms Guide boots with the Aquasteath sole with studs.  I'll never not have a studded boot in the future.  Someday I'll probably upgrade to a pair of Simms waders, once they start making the gravel guard out of the breathable wader material, not the neoprene they use currently.

has anyone noticed how cabelas wading boots fit?  last pair of wader boots i sized 1 size up to a 12 and it was fine, but really too big even with the neoprene foot and heavy socks.  most of you size up or stick with what you normally wear for good wader boots? 

Joe,
 
I think you are comparing lug soles to felt, not studs. A lug sole will grip gravel bottoms, mud, or snow, but are no good on the slate bottoms of the tributaries. Plain felt will give a better grip than lugs in these conditions, but can also slip on moss covered slate. Studded felt gives you the best grip for the Erie tribs.

With the backcountry felt boots

Only the first season but I like them, especially the padded shoulder straps.

These are the waders I have, I've owned several of Cabelas breathables and these are the best. A little steep in price though.

Joe, I had the the dry plus and they worked ok, get yourself a good pair of wader liners. A friend has the ultra lite boots and he has had no complaints. I would recommend felt with studs.

How long have you had those waders?  I just got a pair of them.  Only wore them a half dozen times or so.  Just wondering.

I have only had them about 8 months, but I really like them. The anatomically correct foot doesn't get bunched up like some of the feet in the other waders.
