Tahoe I'm in your shoes I tote my bikes around and like the fact there is some low end grunt and really don't want to worry about changing to much that will require attention in the long run, just wondering if OEM or OEM copy would work for daily. I'm sure OEM is not cheap either.
You guys could probably do the steel flywheel, that would help you out both ways. Still has more mass than the aluminum one, but is lighter than stock. I have the steel flywheel and stage 3+ clutch and I've hauled a gsxr1000 in the back with 4 people in the truck at one time and it didn't give me any problems at all. I guess it depends on how much you tow and how often though. But the steel flywheel is a nice compromise.
