hey, I say go for the ibanez, I have an ibanez GRX 40, although mine doesn't have a whammy bar, it has the trem, just not the arm... so I don't divebomb, but me, like a retard, sometimes while playing, will push down on the trem with my hand to dive it, and it stays in perfect tune, so I don't think you'll have a problem... I play my ibanez GRX 40 everyday, and it works for pretty much everything, especially since it's got one humbucker and two single coil, switch to the humbucker for rock and metal, then switch to singles when you want classical, jazz, folk, etc. although, I'm not sure you are looking at the same exact guitar, you might be looking at a grx 20, which has 2 humbuckers, but you could still probably play all kinds of music on it, it would just sound warmer rather then brighter.
