I honestly think you should get yourself a good bread and butter type synth (like the two above) and then a good analog style synth in order to make westcoast music. The above two synths probably won't cut it when coming to synth leads or basses.
What I mean by analog style is either a virutal analog (a digital emulation) or the real deal. Some decent ones are the Access Virus series, Nord Lead series, Minimoog, Juno106, even Roland jd800.
