3 should work fine, you'll just have to adjust the tension (the 2 screws holding the claw to the body). If you try to tune to standard with that heavy guage, you'll probably need to add a spring and tighten the
truss rod, and still may have problems if it's an Ibanez, not sure their thin necks will like that much tension, but you should be fine tuned down to B or A.
