Re: To Brake or not to brake.
If you are on the fence I'd brake it, with a non-indexed version, and get a thread protector so you don't HAVE to use the brake.
I like to do a lot of range shooting with my hunting rifles and the brake is nice for that, then you just verify your dope without the brake and hunt without the brake. Everyone is different when it comes to recoil sensitivity. I see a lot of guys with big rifles that say recoil doesn't bother them, but you can SEE them flinch on the range. If the recoil is really messing with you, your best option is probably to go to a smaller caliber.
I would not hunt with a brake unless I knew I was going to have setup time and no stalking was involved, which pretty well would only be in a blind, or was going to spend a lot of $ on custom molded electronic game ear type setup. I won't wear electronic muffs in the field and I won't hunt with foam or molded ear plugs in.
As for faster follow up shots, I don't think it's the issue you are making it out to be. Now if you want to see your hits it may be, especially if you have to shoot from a poorly supported position, but even on a light 06' with good position and follow through it should be possible to easily get back on target and run the bolt for fast follow up shots.
