Yes, The Rick Roy ones are really nice and light, only about 4 oz. heavier than a MSD-TL flywheel. About half the cost of going full MSD TL, and about half again as much gain in performance, so it works outs.
This looks like a new way to go for a 62T charging type system coupled with a MSD enhancer cdi. You just can't be as aggressive with the compression though.
They're pretty new so If they hold up well, thats the way to go...
I have put a timing light to them as well and the flywheel timing was right on the degree marks!
