found a nice list of what you have to do to unlock the +5 boost for each area, and also what you have to do to unlock the various equipment that have 3 boost slots. though i know some of the boost stats can be equipped on different equipment types. for instance i got the +5 slapshot yesterday and i could equip it as my stick slot or one of my helmet slots. you can have up to 12 boosts but there are 20 different stats, so you still have to choose wisely what you want to use.
