I'll get to the questions first, is an ml-10 longbow fastflight capable? Any interested string craftsman let me know please
Is that a 68" Martin longbow,they are dacron only I believe.My buddy had one and it didn't have any overlays on the tips.You could modify it yourself with some overlays from 3 Rivers,it is easy to do with some basic hand tools.I have heard Chad from recrves.com make a good string.
my martin vision came with fast flight and so do the serengiti's . call martin and ask them.
If the ML-10 has overlays on the tips it is OK for FF if it dosen't I would not try it. Mine dosen't have overlays I called Howatt they said don't use FF.
