I have a Stalker in 30-06 with the BOSS. Great gun, silky smooth action, very accurate, great to carry, points well, hits same POA with cold or hot barrel. Absolutely love it.
Its my understanding that the new guns come with both barrel weights (comped and non) for the reasons you stated. Mine only came with the eardrum buster, but a care package from Brownells fixed that.
Would I get another Stalker? In a heartbeat.
I've had the BOSS get loose a couple times while at the range, make sure its locked down good and tight. (you don't want to LockTite it so you can take it off to clean).
Would I get another gun with the BOSS? No, but only because I reload and can tailor the load to the gun.
If you don't reload, the BOSS is a great thing to have. It allows you to choose any load you want and then tailor your gun to shoot it very well. Be prepared to spend a lot of time and ammo sorting out the gun, but once you do, you'll have a light barreled hunting gun that cuts one hole groups all day long.
