I have all 3 and would use all 3, 1st flemish fast flite. I like its speed its gives, just make sure not to dryfire! 2nd the endless looped excel dacron reason it is easier on limbsand won't pull thru. 3rd and last but still decent is the flemish dacron witch will pull thru if you let it untwist any. Its only bad point. The other string i don't use at all is fer the older carved limbed Excals! Ta da wahoo!
