ok 13 or 14 will be good enough on your bleachers going into div 3 with your boost in attendance due to promotion if it happens for you you will probably just about fill them at 13.
lower tier you can probably leave them at 45 or maybe even up the to 47 or so for your div 3 promotion
you have been selling your courtside seats out for a long time so i would up the price of those to about 135
and on luxury boxes go up to 950 or 1000 since you are selling those out too
