I'm finally 1000 rated (1020 I think) and have gotten pretty consistent with my discs, but I still haven't really found a good way to incorporate rollers into my bag. Any holes where these really change things for you? To be fair I play left-handed (gotta keep it realistic!) so that may change things.
Roller Shots: (actual rollers)
Oak Hill 4 (though throwing righty I can only get the FH there in favorable winds, you can do it more often)
Kaho 2 (60/40 success rate, sometimes it gets ugly - but in competition I usually get the 2 or the 4 out of it)
Kaho 4 (approach shot, if you hit the wall with some cut angle it reliably bounces over and in-bounds - so you don't need to worry about skipping deep OB)
Kaho 7 (the angle just works well, a must eagle against top players)
Downtown 6 (big high roller to clear the early road, gets you often to where a fairway can get to the basket for the eagle)
Pioneer 8 (roller 2nd shot is often the play, though it really depends where you land off the tee, this may not apply to lefty)
Roll Disc Air Shots: (using roll discs to prevent skip)
Lakeside 9 (middle island, lands it 75% of the time, and when it doesn't it is an easy bird)
Harrowing 5 (clear the water safely, without skipping deep)
Coyote 3 (for the safe shot, guarantees nothing fishy happens off the tee playing for a lot of distance down the right side to set up a fairway throw in attempt)
Backwoods 1 (for me the best line is an air shot all the way to the pin, this keeps it from skipping OB)
Backwoods 6 (the safest shot is to crash the wall deep, the roll disc always rolls down off the back wall so you don't stick OB)
Frozen 1 (another hole where it is easiest to land at the pin, it eliminates the skip away)
Frozen 2 (great disc to risk it with, way less likely to skip OB left off the island)
Frozen 7 (thrown up over the top, it doesn't skip into the trees left)
Frozen 9 (doesn't get that long skip OB off a shot that hangs in the air around the mando)
Downtown 7 (if its run it or nothing - the roller disc is your best bet to stick)
Downtown 9 (I power down and throw the roller disc to land near pin and stick, avoid OB)
Island 1 (land near pin, doesn't skip OB)
Island 2 (land near pin, doesn't skip OB)
Pioneer 2 (approach shot, forehand slightly powered down, avoids skipping up over the crest)
Pioneer 3 (righty forehand to the right side, doesn't skip OB)
Pioneer 4 (only with favorable winds, to avoid OB skip - unfavorable wind I use normal or skip)
Pioneer 7 (out over left side, lands and gets knocked around a lil by the rocks to slow down and settles nice)
