Just sold my 50mm L and might need to sell my 135L. I'd definitely consider a Sigma 50mm Art lens and a 135mm f/1.8.

I'm curious - when do you remove the center plate?
As for G-locks, that's Gitzo-locks, so who else do you think would have them? The 'gravity' part is marketing speak, as far as I can tell. They state, "The higher the load applied vertically to the leg, the stronger the lock," but that would apply to any threaded fitting. I find the RRS leg locks easier on the hands when opening/closing them, because of their shape.
Interesting that you call out the feet, though. I like the idea of spikes covered by the rubber feet, vs. having to change them out (and having to pay extra for them). Having said that, I've only rarely needed to use the spikes I have - the teardrop feet on the RRS legs are significantly wider, and shaped so that they contact the ground even at wide leg spreads. If I do need to use the spikes, the RRS ones are significantly longer and dig deeper (the threading is the same, though - so you can add RRS feet/spikes to Gitzo legs and vice versa).Both are excellent products. Differences are degress of excellence, both will serve you well.
This is really the bottom line - you can't go wrong with either.
Reason for new version is probably limited usability with extenders.
I compared my old 200/1.8L with 200/2L IS and f/1.8 is sharper with 1.4x III and 2.0x III extenders.
Really? I just did a comparison a week ago over at TDP, and it seems very far from it:
Am I missing something?
