Another one that you might consider (if waiting a bit is an option, that is) is the new McMillan A5. Check the forums over at www.snipershide.com
for some advance pictures of some of the first models being shipped to customers. Kelly McMillan frequents that board, and IIRC, the A5 is the result of the inputs of a lot of the members there and the small niggling dissatisfactions w/ this-n-that on the A2 thru A4. You know... Well, I like this part of the A2, and this about the A3, and the A4 has this nifty feature, but I can't stand this other aspect of it, etc. The picture I saw of it got my attention! Colors chosen were butt-ugly IMHO, but then they were meant to be camo, not pretty.
