Roy, the horn tips are traditional English style with tapered hole fitted over tapered limb tips. There was already a tiny keeper string hole in the upper - a good addition for making sure the string stays put when unbraced.
Yeah Chuck, I really like the performance and feel of TS strings. I use it almost exclusively.
Pat, not sure of the weight as my battery died in my digital scale, but they are a little heavier than POC and much tougher.
