Jenvey are more expensive because they would no doubt be a lot better than OBX. ITB's need to be quality to work properly. I have heard mixed reveiws on the TODA ones. I had TWM itb's on my Bseries. They worked well enough but also suffered from a slightly sticky throttle. Was manageable though.

Kinsler would have to be no:1 choice, but you pay for quality and ITB's are not cheap.
