Having played all of the sevens mentioned so far I can say they are all awesome.
But, ultimately, RG1077XL > RG7620 > RG1527
The 1077 is an awesome innstrument, and if you love it, great. I've got dibs on one here in edinburgh so we shall see how that goes...
But i'd take the 7620 over the 1527. Prestige snobbery (not a slight against you my friend) the 7620 is technically better spec'd than the 1527 - a new 1527 is MIK now, with New 7 pickups and an Edge Pro. The 7620 is MIJ, cheap as hell, and comes with the older, slightly different New 7's. While it doesn't carry the "Prestige" name, back then it would have been "prestige" if Ibanez made J. Customs to stick the J.Custom logo on the 1077XL.
Its just a better guiar for less money because people aren't aware of what it is worth compared to a 1527 - which is still a current model and there is plenty of online reference prces for.
Also, Wizard I > Wizard II. I just prefer the 7620 neck.
Hope that helps
