Ya might find your speed increasing if you switched to a harder pick than a thin one. I've seen slow motion video of thin picks and they kinda flop all over the place. I think ya get more acuracy without having to wait for the pick to return to it's 'straight' position every time.
Ideally just keep a bunch of different picks on some two sided gaffer tape on your mic stand. Use the hard, small picks for shredding...toss it away and grab a lighter pick for more expressiveness or chord strumming.
Put your web address on a bunch of picks and toss em into the audience.
