Slapshock, In drumming, there is no right or wrong.. however there are certian guidelines that you have to follow, like not playing with your arms and stuff like that..
The dave weckl snap tech, is very good. gives clean concise tone to your playing, very versatile too!
The standard wrist down tech, has alot of power, makes it flexible for you to move around your set.
For as long as your wrist does not hurt when you play.. your doing it right. but if your arms get tired, press on! dont stop, if your arms hurt, stop! coz you want to be playing for many many years..
