Left Foot

So the last couple of days I've been trying to do research on the best technique for left foot work. Sadly, the answer (like with so much of drumming) seems to be "do whatever works for you." This is not helpful advice when you don't know what works yet.

I've got a packet of problems which mostly add up to
1. No endurance in my left foot
2. Independence problems
3. Injured left foot

For some reason, increasing speed with the left foot also just seems harder than with the right...I think because you don't get the rebound.

Anyway, I'm really frustrated. I keep thinking I'm going to find some key to make it easier...but I suppose it just comes down to repetition.
