No, I have never had any interest in MPPT.
If I ever get a Class A, and I am feeling beyond rich in installing a 800W system minimum that's 24v panels, maybe then I'll spend the schekels to test a bigger MPPT. 20 Amps, is mouse nuts and PWM territory, AFAIAC, 10 gauge wire will handle it just fine, heck 12 gauge wire will too, for most applications.
Besides, I know it's time for you to sell your panels and Charge Controllers, to get and test the newest, bestest, badazzedest 2015 Chinesium version of MPPT. I don't want to rain on your parade or deprive you in the name of science, or steal your thunder announcing the latest and greatest from the Full Timer Side. :W
Or maybe give that slacker Mena661 a poke to get off the pot and on some forward momentum on his new roof job on his RV.
