I will most likely use the Tamiya spool up front so I won't have this problem...your feedback helps if I decide to use the front one-way. Thanks

So now if I use the front spool, I need to get the TA05 locked center pulley. To get the proper 2.25 drive ratio which everyone is looking to achieve.

Or....I can just stick with the stock 415 stuff...although the white diff pulley's look trick
