2016's will work great for you with 125gr tip. If you want heavier, 2018's with a 150-200gr tip should also work. I shoot 53lb @ 29" with a martin dreamcatcher and use 2018's with 125gr tip.

3555s will also work but will be light, that you might want to add wieght tubes or front and back brass wieghts with the GT wieght system.
