RE: arrows for lighter drawweight
I used to use a PSE Bandit with 24"dl set at 34# at first and as high as 43# towards the end of it's use. I always used a 1816 with an 85 grain broadhead. The spine was right. They flew fine.
There is also a 1916 if you want to shoot 25 inch arrows with heavier broadheads. That would be a heavier arrow. Not sure if they would be over spined or knot. You might need to put a heavy tip on it if the over-spine makes the arrow hit to the left.
