I have both, the LSS and a Choate UV. Both are great stocks. Even if you get the Choate tactical with the bells and whistles, it will still be close to what you have to put in to the LSS or the HS3. Personally, I love the LSS I purchased because I was seeking a light weight solution. I wanted to the XLR Carbon Fiber, but I couldn't justify ~900 for the chasis.
