hmm i agree for the whole dive bombs you will be best suited for a guitar with a nice floyd rose which i don't recommend unless you can get help or have a good amount of time learning how to set one up properly. The GRX don't have them for what i see, These RG prestige series seem maybe a lil more towards what you want. I suggest playing any of these before you buy them btw. I personally like ibanez cause they feel strong yet have really nice necks. Hvae you looked into ESP or Jackson?
