I've wanted a CLX for a long time, but never pulled the trigger. I had a sigx, a classic, a gp3 w/2/50/2 power amp, and 3 different ULs. They all got me about 90-95% there. Some day...
I'm kinda planning the opposite. I may pick up a used FX8 or a new Ibanez AZ24027, but have a few pairs of mackie monitors and a few Ibz 7 strings for sale right now.
I've met a handful. These are the ones that come to mind...
Lynch (three times)
Jon Oliva
Steve Morse
Rod Morgenstein
Derek Sherinian (actually had a few phone conversations with him)
Tony MacAlpine
Dennis Chambers
All the guys in Phish
Started a new project in 2017 or so and life got in the way. This is a rough mix of one of the songs I've recorded since.

My 2210 was my gigging amp for ober 15 years. One of the few amps I regret selling. The JVM 410 and Ultra Lead are the two from your list I like the best. The JVM can get similar gainy tones to the 2210 and the cleans are 10000% better. And can get other heavier tones too.
