A few quick thoughts here. I second the VTG-Luxe. It is slightly heavier than and not as pretty as a Cyclone but it is nearly bulletproof, a useful property when you're touring 135,298 miles from the nearest bike shop, or even just 10 miles. Yes I did have a chain jump out of a quick-cage once. It was on a Vx-S (the intermediate cage, the GT version is longer still) when the chain shifted off the inside of the small ring. I have no idea what sort of bouncing around allowed it to jump out of the cage too. (The chain got stuck under the rear tire and I skidded to a stop, wearing a flat spot into the chain's side plates. I popped the chain back on and continued riding, then replaced the chain when I got home.) However this episode has not stopped me from using them. They are just too danged convenient.

One thing to check is the inner plate of the cage. IIRC, on both the VGT-Luxe and Vx (or is it the Cyclone-GT?) it protrudes upward above the pulley and possibly hits the adjacent larger cog. I recall seeing that problem once and adjusting the position screw (the B-screw?) to eliminate that interference. A big plate aids in shifting up but could limit the cog size unless the hanger is longish.

FWIW, the Vx appears functionally equivalent to the VGT-Luxe but perhaps not as pretty. The Cyclone (1st-gen at least and I don't recall the MkII) has a nifty feature where the cable housing fits into a moving part of the parallelogram. This allows the angle of the housing to rotate with the parallelogram so that the cable always emerges from the cable at zero angle.

I can't decide whether that deer head logo is supposed to be the front of a motorcycle or Batman with his wings extended.

Edit: I check various RDs. The protruding plate I recall is the outer plate, not the inner. I had trouble on one installation with it hitting the second largest cog on a big-cog FW.
