What are the best Aggressive skates for my team?

This is the deal. Me and me best firends had been wanting to strat our own stakeing group for the longset. We are martail artist and have alot of cardio. As a group We chose to use the winter to build up our stamina, cardio and be in tune with our bodies during the winter until spring. Then we would buy skates. We want to be able to do tricks, grind, and have speed but we are kind of lost on what types of skates would be good for us to start saving for. Any help?
