31 yo been skating 1.5 years after a 12 year break. I skate big transition and ledges. Two different boards. If your going to be doing bigger transition, 6 foot plus, go with 56-58 or bigger. You could get away with smaller but as an older person pumping is a lot of work. Save energy get big wheels. If skating ledges and transition under 4 feet I use 54 mm slim rictas 99a. Again could get away with smaller but pushing/pumping require a lot of energy.
