I specifically mentioned Vais in my post for a reason. They make a good brake, but they do kick up a good bit of debris. I do not claim to have kept up with all recent innovations on brake tech. It seems you have pretty well nailed down the terms and usage patterns.
I have used Braked rifles, and non braked. Each have their place. If it is a 300wm that i will try to practice at long range with, BRAKE PLEASE!!! If that makes me a pussy, well ok!! Putting 50 to 100 rounds down range in a days time with a 300 win mag in practice at 800 to 1200 yards is NOT my idea of a Fun Day!! It sucks, even with a good brake! Not a whole lot of people really CAN put that many rounds down range, braked or not, with heavy 300 win mag rounds. I am kinda sorta one of those, but prefer not to be

The new setup will *HOPEFULLY* weigh in at WELL over 17 lbs.... I am still considering the BRAKE on the new 7mm RM.... not really decided. But i will NOT be fluting, as i Want Weight!! More Weight = Less recoil! haha, yes, I am a pussy!! I will gladly lug the extra "few" pounds of weight to the shooting spot!
Good luck, and Consider carefully sir,
