Hi Les.? My G11 is the same as yours, no bearing in the ring gear.? I have the same upgrades you're proposing, and typically get 0.6-0.8" guided.? I asked Scott once if the inner bore of the gear should be greased and he said yes.
I'd say the single biggest effect on guided performance I've found is the worm bearings.? Get a bad one, and you'll see spurious spikes that are too quick and of too great an amplitude to guide out.? I've had ABEC 5 that outperform 7, a bit of a lottery the ones you get. So I get a bunch, put them on my old steel worm temporarily just to feel the smoothness as I spin in hand.? PE is usually slow enough to guide out, but not a noisy bearing.
