I wouldn't presume to speak for Troy -- and he follows this board from time to time and could better answer your question anyway -- but the stock that seems to be the most popular for Hunter rifles at this time is Mark Pharr's.
Mark basically just corrected what were perceived by many as a few minor faults in the Nesika. He has two slightly different versions available: a 'standard' style and a 'split finger hold' style.
IMO the progression has been Brown to Nesika to Pharr...and most poeple that I talk with seem to think that, within the current rules, Mark's stock will be hard to improve upon.
Mark's in Round Rock, TX and his ph is: 512 246 7563
