Can't go wrong with a Fortress Anchor, check them out on their website. I found one (I use it as my back-up anchor) on e-bay for 1/2 the price of new. Main anchor is high-polished s.steel Delta (plow style)
Welcome to the board & Lake Travis....can't believe S&S didn't give you an anchor...call John at U-Float-M, he has several used ones cheap. 512.226.4565. A scuba diver from HOU retrieves lots every summer from the favorite party spots & sells them to the gas stores.
