Drum practicing gadgets...
Are there any gadgets out there designed to help you improve - or gadgets for general wrist/hand/ankle strength that can be used for drum purposes?
Examples would be the GripMaster (not specific to drumming), Hansen Futz pedals (are these any good?), the wrist powerball, and various weighted sticks...
Thanks for suggestions!
I'd give my left hand to be ambidextrous.
