Pre-Loved Unifoil Progression 13.5″ Cover 7/10 condition, Few scratches, but nothing major. The progression tails are tuned to a neutral foot pressure. They have evolved out of the Shiv tail, our most popular of the 3 packs we’ve sold. The Progression tail is fairly thin, giving it some extra speed and pumping efficiency over the Shiv. I’ve also pulled the tips in a bit more for sharper angles in turns. RRP $365, selling for only $146
