Re: Which Manners?
I have a T4 and a T5, really like both (I have big hands.) The T4 is a bit simpler to handle and get behind. T5 is exceptional as a thumbhole stock, but shooters usually love or hate thumbholes.
Keep in mind you might be setting up a rifle used by lefty shooters as well as rightys. If you get the T5, get with the righty swell, it works equally well for shooting lefty.
