How do you guys feel about a Brison 2.4 on one of these Katanas? I'm having trouble deciding between the Brison or an MVVS 26 with pipe. The Brison has been reliable as a rock, while the MVVS is has been finicky and very peaky. I was also considering goiung to a Pitts type muffler on the MVVS as well.
I'm leaning toward the Brison simply because I want something insanely overpowered and reliable, but on the other hand I don't want to kill the foamy like wing loading or the airframe.

Any thoughts?
