64 better for carpet, it allowes you to adjust for rollout more accurate cause the teeth are finer. 48 better for outdoors less suseptable to striping, teeth are stronger

im abit confused on this.

when you say 64 pitch you can fine tune your ratio/rollout is this because the gears are smaller therefore you can fit alot more sizes giving you a wide range of spurs to use?

or is there a different formula of working out FDR?

my understanding is that if

48 pitch : 70T spur divide 20T pinion multiply by internal ratio of vehicle = FDR
64 pitch : 70T spur divide 20T pinion multiply by internal ratio of vehicle = FDR

would give you the same number.

To have the same FDR and near equal sized spur gears, you would need a 70 48p to a 96 64p spur. A 70 spur would be quarter sized b/c the teeth are much smaller. With a 70-25 tooth 48p combo, each pinion change makes the FDR change by about 0.3 and if your running 96-34 tooth 64p combo, each change makes about a .19 FDR change.
