The one key feature you should be looking for to help make a formidable slapshot is the stick bend. There should be a slight curve and a closed blade angle. A high lie can also be useful, as can a medium to high flex and a low to mid kick point. Again, these are more conventional features so you may want to take the time to find out what you truly prefer. It may be difficult to find a hockey stick with all these features included so try to analyze your slapshot. If you can find out what features of the hockey stick work well when you take your slapshot, then these can be enhanced.
