If you're debating HTG and Classic, why not go to a thinner monte carlo style stock with a little higher comb and buy a Sako Hunter? Better than either in my opinion.
Got to handle an HTG last night. Granted it wasn't ideal as the rifle was a 12#'r with a 50mm obj scope on it. You absolutely needed a stock pack for optimal cheek weld/line of sight with his scope and ring combo (med rings). I didn't like it like I thought I would. Glad I didn't have to pay $500 and wait 4 months to realize that!!!
Trying to get my hands on a Manners SL now...and compare it to the Classic.
That's the nice thing about coming on here to ask about Mcmillans (or a lot of other things): there are plenty of folks that have BTDT and can save a guy a lot of money trying to do R&D himself.
The one thing I do a bit different is have the action skidded forward .5 of an inch over standard. It mouses up the way the rifle looks at the tang area alittle bit. But you have ALOT more room on the grip for your hand. I do all mine that way.....
