When I swapped to disc on the 63, the difference was night and day. Not saying that a properly set up drum won't work great, just saying that with a lift and bigger tires that a front disc axle will probably work a little better. I've been guilty many times of making it faster, bigger and able to do more first and addressing stopping last. I try to address stopping first now as my heart can't take the pucker factor when it won't stop as planned.
