Yes, spectra does not stretch nearly as much as poly. I have always used curved anti-rotational handles made from poly rope but two years ago got one make from spectra. I noticed that after a couple of weeks my 56 year old elbows started to ache more. I also feel that right off the buoy the spectra handle gets me moving faster to the wakes with less of a delay which I liked. I could not believe that just 5 feet of rope would make that much of a difference as my poly rope handle was from Brenda and she basically doubles the line so its already quite stiff. As an experiment I hung 90 lbs from the end of each handle and left them for 30 mins. The 2 month old spectra handle stretched 1/4" and the 2 year old poly rope handle stretched 5/8". I would expect a 2 month old poly handle to stretch even more. To help "soften" the spectra handle to make it more elbow friendly, I fid a 2" long piece of round bungee tie cord into the rope. This gives the spectra rope something to "collapse" against when coming tight which was way easier than figuring out how to ski with ZERO slack!
