fast flight or not?

[D.J. Carr]

How do I know if I can use a fast flight string?
I have a 52" Red Wing Hunter, can I use a fast flight?

[legends1]

I think not! I would stay with D50.

[dbd870]

yep; I've heard no ff on them.

[Cold Weather]

NO do not use FF

bow not designed for it.  You will ruin your bow.  Dacron only

[Terry Lightle]

Not if you want to keep shooting it

[rick7]

b50 i would rather be safe than sorry

B-55 is the better polyeser material.  

Some folks have reported good results with HMPE ("fast flight") materials, but it's a crap shoot.  Several years ago there were some people that loved B-75 and PENN 66...and some people blew up bows with them.

My personal opinion is I'd never use anything other than polyester on an old bow.
