I sup foil. Rode the 880/140, then 880/120, then 880/130. Now 890/130. But I was real impressed with the way the 130 made the 880 feel. The turns felt like it was on a rail but not locked in. Like really powering through the turns. Kind of hard to describe but put a big smile on my face. Armie has always said the tails are the cheapest way to change a front foil. I also read somewhere some one else had good results doing it. It was a stepping stone to buying the 890.
