Breedt only had issues with the NTC older bushing actually. Some reverse lockout issues when using the forward shifter positions, remedied by a small simple modification to the reverse lock-out ramp due to the new resting position of the shift lever.
Mountune is a very nice piece, but that pricetag was always rough, as mountune tends to roll that way.
The TWM has been on my mind, but I'm liking the JBR so much, I doubt Im going to fork out even more cash to test it. I can shift entirely too fast right now as it is, with very precise mechanical feel, I would be surprised if anything can improve it for it's price tag. Then again I was super skeptical about the JBR performing any better, and it did, lol!
