Yup, I'll go with mooman about positioning etc. even tho' it's a bit frowned on by the purists. Be comfortable!! My only difference is that I use the Dunlop .46 which is a bit soft but I'm often amplified so it makes little difference. Get a handful of different picks, gauges, nylon/plastic and see which you feel happiest with. The 'grippy' bit certainly is good advice particularly as you start.

Happy playing, Nick
