How 'good' is a OS40FP compared to other .40's that are on the market now? I have a 40FP in my PT40, and it seems fairly stout in that plane..I typically fly with it less than 1/2 throttle (never have to nail it unless i get in trouble showin my butt hehe)
I picked up a Hanger 9 twist 3d at my LHS, they were on sale and i heard they were a great fun fly model, and was thinking about putting that 40FP in it..or should I get something else? I am not interested in "3D", per se, just in minor acrobatic stuff

no hovering or trick stuff like that..if not that 40FP, what would be best (2 stroke, semi-affordable)?
The 40FP will do what you want with the twist. I'm sure you have probably found that our by now. Since you don't want to do 3D and simple aerobatics, the 40 would be ok. Probably not too much vertical pull though.
