If demand allowed it I'd be more than happy to get some higher gears made. My guess is, that while a limited demand exists, there is not enough of a demand to allow a run of sets to keep the cost down to a reasonable level. I'll look into it though and let you know. Also, it would be helpful to me to get feedback on the potential demand for those "top end" gears you are talking about. Feel free to E-mail me or call me at 818 985-7660. Thanks, Mark
