The brake on the T3 is a Harrell's Precison, which is definitely a "best buy". Effective and inexpensive.
The brake on the TRG is a factory Sako. They are expensive, and quite frankly while it is decent, I have shot better brakes, like the APA Fat Bastard.
As far as seeing hits, on the sporter weight gun, I have a harder time. On the TRG, it is pretty easy. From the prone though, it should not be an issue, but a lot depends on how you drive the gun.
