If stripers are your goal and you'll mainly be fishing lakes then you'll probably be better off with a peddler.Peddle kayaks are generally more stable,offer hands free fishing and you can gain more speed with less effort.Some of the down sides to a peddle kayak are price,weight and they are not very practical for fishing smaller waters or river with a lot of shoals.The up side to paddle kayaks are price,weight and being able to access waters where peddling is not pratical,although companies are now offering peddle kayaks in smaller platforms and lower weights.
One of the best piece of advice I can give you is to go to some local kayak shops that let you demo and paddle or peddle as many as you can.All kayaks are differant and you really wont know what will suit your own particular needs until you spend some time in them
