Bozman71, I kinda doubt if the serving will increase wear, but really don't know that for a fact. Due to the smaller diameter of the string at the loop of an endless there has to be more pressure exerted on the limbtip though. When I make an endless loop string I always pad the loop by adding several short pieces of string material prior to serving the loop. I believe that this is especially important when making the string out of the newer, non-stretch material such as Fast Flight.
Naphtali, yup up the road a piece but not too far. I do on occassion head that way to hunt though. Many years ago in my logging days, I stayed in logging camp up there. It's awful pretty country.
It seems to me that a flemish string has to be somewhat heavier than an endless loop string of the same length and strand number. The strands on an endless basically run straight from loop to loop, with some minor twisting. Due to the more intense twisting on a flemish, to achieve the same string length the individual strands have to be longer, which equates to more weight. Whether that has enough of an impact on velocity to matter I really don't know. Man, I'm getting a headache. :-)
