lol, ARO...its been a while since I've heard it myself, Vin and i used to jam to it quite often.As for the lessons, just let me know whenever you feel that you need it...and yeah spiral architect is awesome.
I've personally never been a fan of Hz's.Pretty dry and no clarity IMO , so i would swap them out if I were you but if you already have your sound sorted with the axe through the x3 then that's good.I use my prestige's, GT10 and Blackstar series one 100 6L6.
