Its just that we're talking about warming up, and you brought up tapping, and I thought, "Whatever floats your boat."
Anyway,I know a lot of people who use their index finger, my middle finger is no weaker, but I usually like doing things differently.
Anyway, I like the index finger because I can go faster and tap stronger. I think the middle finger is favoured because you dont have to reposition your pick. But if you find the middle finger way easyer, than do it. With a little practice, I found repositioning your pick wasn't that hard, so I tap with that finger.
If you download the video for Eruption off kazaa, you can see how Eddie repositions his pick, thats kinda how I do it.
And God said, 'Let there be rock!'
