I agree with ImB, with this you can use it with anything. Onroad would be cool, but I have no place to ride it frost reaks havoc on roads up here, not everybody is into choppers, and with a top line .21, not everyone has a buggy to put it in. Although I do like the .21 Idea because I can bumpstart both my rides!
But my vote is for a top line radio, and it doesn't matter what brand.
