RE: OS .91 props.....
I don't understand the ques..which style?
And to your next...exact application, you mean your specfic plane/engine combo?
No.
I do, however fly Cap's, Extras and other 3D planes so I know about what your seeking, I think.
The lower pitch props slow you down, and the wide get's you better bite without over revving.
APC's are known to be the best on the 91-100 class engines.
I do know that at 13-14 bucks a piece, it gets spendy experimenting, but it is what it is.
Try both if you can afford it, and have the clearance.

RE: OS .91 props.....
By style, I meanat wide vs narrow. It's got a VERY wide Graupner 13.5x8, I believe, right now. turning at about 9600 RPM static @ 3000' of altitude. It's wide, right to the tip. I'll try an APC 14 x 6 and see what happens.......
