Rebel Hog the difference on stings, is actually how they are made. The regular string is made of dacron and is looped then twisted as in recurves and has ends and middle served.The Flemish is much better as it is 2 strings twisted and spliced and then served it is made of fast flight.Also so that every one should know, you do not put deck and string wax on mainframe. Put it on center serving of string! Yes its so much better to be able to twist string and wax it and keep on shooting and shooting!
