The best cleats for ultimate frisbee?

theres no section for ultimate, so i thought the soccer section would be my best bet. i am looking for some very nice cleats. if you've never heard of ultimate, it is non stop running, jumping very high, and diving/laying out. since there is lots of running from 0 to sprint speed, to stopping again, then accelerating back again, i need a cleat that will give me good grip but will also be light. i also need a light cleat for skying people for the disc when it is in the air. and also from jumping, i need a cleat that has thick cushioning for my feet and especially my heel, since i bruise my heels a lot from the shock and impact of high jumps at full speeds. the pumas i have now are cheap and have no cushioning/shock absorption. also the grips are very wide & thick, which is pretty much only good for soft muddy terrain. i play on lots of mild to hard ground, so i need a smaller grip that digs in well. also extreme lightness is key since there is so much start & stop running & jumping.thx
