I've livestreamed and done several RGH Trinity video tutorials mostly focusing on the "Ace V3 w/CR4 speedup" technique. I've also experimented with the "CR4 Muffin" technique using the Matrix V1 chip (also possible with CoolRunner Rev C).
I believe that the "Muffin" install technique is a better fit for first timers as it's an easier install, but the Ace V3 CR4 method is very good too.
