I can't remember if that one was "Fast Flight Compatible". Might contact Martin and find out for sure. If it is, I see no reason not to use a "FF" type string on it--just make sure it's built properly. If not, I'd stick with dacron.

With carbon arrows, just be sure the over-all arrow weight is high enough. I like to stay with at least 9 grains of arrow weight per lb of draw weight (9 gpp). It's quieter and less shock that way also.
