Brenda here with In Tow. Based upon Gordan's slalom instruction expertise, I view the spectra rope as being a good training tool for 15', 22', & 28'. So, I offer spectra sections that can be attached to your slalom mainline to replace the polypropylene sections. This is much the same slalom training mindset as my mid loops; it's all about getting from one line length to the next! Spectra rope, with its zero stretch characteristic, is not conducive for short line skiers.
