I also prefer the center-grip over the rear grip. The Zytel stocks are okay, but I like the H-S Center Grip Stocks or Center-Grip by McMillian. I enjoy the Longer Range shooting so I would pick a 308 based case that has been improved or something built off of the 284 Win case or a WSM case. All of my xp's are customized and I enjoy them more than any of my other types of specialty handguns, thus my user name "xphunter" XP (for XP-100's) Hunter (because it is my primary handgun to hunt with).
