Fly fishing the Yough Ohio Pyle and above

I have fished the tail races and down near the dam.I really want to fish the remote areAs from Ohio Pyle and above.I have a bike and plan on riding the trail on up river.Any tips,techniques,what kind of flies to use and maybe a spot or two to get me started would be greatly appreciated.I live in Belle Vernon so if anyone would like to tag along,split gas etc I'm in.I know its winter but I wAnt to be prepared for when early spring comes.

The river itself is a good bit different from the stretch below the dam, as it is near Ohiopyle. 
 
As Loomis noted, fishing the deeper slack pools.  Much of the river below the falls near Ohiopyle is either large deep slack pools (many seem to have little current at least on the surface) or all out rapids (some are fishable if boats aren't around).  There are some channels and "inbetween water" below, but not very easy access beyond the first 1/2 mile below the falls.  A bit more above the falls on both "inbetween water" and access.  The access below the falls is mostly popular "watching" spots or put in / pull out spots for the white water boaters, both have decent hikes off of the bike path to get to.  I'd guess that some sort of intermediate or sinking line might help, since many of these pools are pretty deep.  If you fish any of the deeper pools near Belle Vernon, I'd take what you know from there & use.  I've only fished this area a few times, mostly with spinning gear, since it is so deep.  I have rafted it 15-20 times, but have never tried to take along gear.  Some great looking water if you are brave enough to take along your gear on a white water boat.  I've ended up floating through rapids with a capsized boat about 1/4 of the time rafting, so taking along gear below the falls probably isn't a good idea until you are comfortable with the river.
 
Below the dam, it is moderate moving water with channels, and not many heavy rapids, which is much easier to wade around from spot to spot.  It slowly transforms as it gets to Ohiopyle, into what I mentioned above.  Along the way are some not so deep, not so slack water pools, similar which is more comfortable fishing waters to me.  Renting a kayak/canoe and floating the portion between Confluence and Ohiopyle is fun & a good way to get to some very nice water.  That is where most of my fishing has been.  I also think they stock this section more, but definitely a bunch of fish below.  I have also waded a bit above the falls, and found some nice stretches.  That is where I would recommend going, mostly due to my personal preference in water type.  The deep pools below look great, but a different kind of fishing for me, especially using a flyrod. 
 
Also, be aware that the boating above and below the falls are much different.  Above, those on boats can control around you a bit more.  Below, if you are fishing the wrong spot, you could really hurt someone altering their preferred (safer) route, or end up taking a swim yourself if a bunch of first timers in a raft can't avoid you.
 
Although not really tips for flyfishing, hopefully you can use.  It's a great area to fish and float.

personally i like fly fishing from west newton bridge  down to layton,,many great spots,,,,trout, smallmouth,walleye,,,just throw some streamers and buggers,,nothing like hooking up with some smallmouth and walleye throwing flies,,,,smithton is good for walleye
