Try using a lot of double stops, like chuck berry style fourths and stuff, maybe work some penta stuff in.
I like the harmonic minor for that exotic surf stuff, use a lot of trem. picking with it and you'll be sounding like a brilliant surf guitarist that knows more than just 12 bar stuff (but learn twelve bar forms to).
That should help you, also study who ya like as far as surf guitarists (I'm not familiar with many...)
There are only two important things in life - There's music and theres girls, not necessarily in that order....
