I'v run all except the powder pro's and a friend of mine has them, don't know it he likes them or not. First over the stock skies I had the simmion'd not bad, big improvment over stock, the stockers push alot, simmion's are like on rails, but they tire you arms out on a long day because they only want to go straight, My King kat came with the parapligec skis those F*cking things almost killed me no steering control what so ever, the best was finally the C&A Razors, the most awsom ski ever make will take my 144"king around corners better than a Rev( I can run down all the REV's I run with) But even on the 300-400mile long days my arms aren't tired. I run 8" of carbide on the Razor and have 6" on the stockers and Dual 6"on the simmions.
