If you want to do it right, save up some extra money and step up from the Choate, especially the USS. I've been behind a few Choates and really can't find anything to write home about, other than at 6lbs it makes a great paper weight.
I had a few various H-S stocks on my Remmys, but turned into a McMillan slut. It really is worth the money to me, and I've got a wife and two kids to feed on my salary.
My new build is getting a Manners T4, they are a bit cheaper than McMillan, and the ones that I've felt were pretty ergonomically correct for my hands.
Buy once, cry once boss...I'm a believer of that one now.
