Having wheeled with t18 & np435, I agree with boat rowing. Slamming between reverse and 1st can be cumbersome.
Having shorter throw and OD would be ideal, nv4500, zf 5 etc
Ive only made a few rides since, Life hit pretty hard, on april 8th of 22' actually.
But I have greased with this before each ride, no issues yet. Obviously too early to tell anything meaningful. Seems kind of a cross between antisieze and grease...
