Yamaha DTXpress/DTXplorer/DTXtreme

I developed CTS due to drumming. I played professionally as a rock
drummer and developed it mostly in the left wrist.  Looked into why
and discovered it was not WHAT I was hitting, but HOW I was hitting.
Drumstick grip, force and constant hitting can cause CTS and it can
become very painful. What I did was see a good drum teacher that knew
about the "Moller" technique. I had a good drum instructor that
introduced me to Jim Chapin, and Jim taught me the Moller technique.
Basically it involves proper stick grip, and enables one to play with
speed power and endurance due to facilitation of proper hitting
technique. My advice is to find a good drum instructor and take a
couple of lessons just on grip. My CTS is not as chronic now and I can
play harder, last longer and have a lot of power when needed. Because
of a light stick grip, but using the power of the forearm for accents,
my wrists do not get hosed playing. Also go to "Tiger Bill's" website
and look into the Gladstone technique. When I started playing rock
drums over 25 years ago, I thought I had to come on to the drum with
all I had, so I played like that for years. I aimed for the bottom of
the drum and played very hard, being a rock drummer heh. The Moller
technique taught me, I could maintain the power, but the stick grip is
very light. Gladstone is a great technique to learn as you 
let the stick "drop" before hitting the drum as the stick has attained
kinetic energy, thus let it travel the rest of the way to the drum and
the wrist does not get shock coming from the stick when contacting the
drum or any surface. I can play on metal plates if I wanted forever
and my wrists would not have any stress on it. This is because those
techniques cause one to "throw" the stick onto the drum. The forearm
supplies the power. Excellent techniques for speed as a humming bird
can flap its wings a lot faster that a Do Do bird. It took a while to
re-learn as I had over 20 years of improper technique under my belt. I
re-learned my grip, and use Moller now. Nothing wrong with your pads
at all. Not to pick on you but please look into your technique as this
can make or break our enjoyment of drumming.

"I can only last an hour at most before my lead hand starts to cramp
from the pad's vibrations."

With Moller or Gladstone techniques you will not only get rid of any
issues with your wrists, but drum longer, harder, faster with less
effort. You can be the animal you always wanted to be on the drums!!!
