Looking for a new pedal for my 8 year old son. The Pearl Export Kit I recently acquired for him came with a p-100. While it's a really smooth and well performing pedal, it is the model that has no beater angle adjustment which I think is crucial while my boy has a small foot. I'm considering the p-530 and the p-930. Leaning towards the 930 because of its range of adjustability and the fact that the foot angle is not affected by a beater angle adjustment. Not sure if this is the case with the 530. I also prefer the way the p930 mounts to the hoop and that it has a floor plate as my son has not yet learned to keep his foot in a consistent position. My only concern is would the longboard be more difficult for him than a short board because of his small foot? Thanks in advance for any responses. FWIW I'm looking to buy used and get either a 530 or 930 for $50 in excellent condition.
