I am not super in depth knowledgeable on a lot of long term suppressor use ins and outs. I was looking at a few different suppressors and I was reading about muzzle devices (brakes or flash hiders) with integrated suppressor mount to them. (I think it is called HUB mount?) On one site, in the description of the brake, it was mentioning how it greatly reduced blast baffle wear and also reduces recoil. While it did not specify the recoil reduction was with the can on or off, I am going to assume they meant with the can off. But the main interesting thing was the reduced wear on the blast baffle Vs using a direct thread. I was actually planning on a direct thread, but now it has me wondering about it. So is there any difference in suppressor sound and/or performance when using it direct thread Vs using it with a brake and a hub mount? Does using a brake and hub mount really reduce suppressor wear? If so, how much compared to direct thread. How many rounds are we talking here about to make a noticeable difference? A couple thousand, or more like 10K+? If using a brake and hub mount, would it increase the life of the suppressor by XX number of rounds over a direct thread? I'm sure there are a lot of factors that play into it like barrel length, caliber, semi or full auto, how hot you get it before letting it cool, etc.. Just slowly trying to learn some stuff here. |

Hopefully this is helpful. As for your wear questions, yes a brake is going to be the most “protective” mounting solution for your blast baffle. As far as how much vs other options, I don’t think there’s any way to put a metric on that as there’s so many variables, like barrel length, ROF, suppressor material and construction, etc. I believe @green0 said that brakes will typically meter a little quieter on many suppressors than a flash hider would. Not sure it would be noticeable though. |

In addition to what bluedog posted there's a long running thread on here with anecdotal info and pics from members https://www.ar15.com/forums/armory/Blast-baffle-pics-with-approximate-round-count/20-447860/ I have brakes on all my short 5.56 and .300blk that run supers |

So I have decided to go with a plan B style muzzle brake and adaptor for the can. Is there any real discernable difference in going with a brake with a large single port such as this one Vs going with something with several smaller radial ports such as this one Does either one make a difference once they are inside the can, or is that something along the lines of picking at nits? |

I would highly doubt that there would be a discernible difference. |

The short brake you listed shows out of stock. Look at the Aim Surplus site. They have an "In House" brake and mount that I am running on 2 of my SBR's. They are bored to 9mm size and run 9mm down to 5.56. They are also 1/2 the price of the one you listed. |
