Your right, new tire technology and good track prep means a smoky burn out is not needed,
They are fun.
I do not think they are that hard on the equipment, you are just cracking the throttle, tires are spinning because of low traction.
I generally just go to the tree (before the tires grab) and get out of it, but then do not brake very hard and end up a ways out.
I back quickly, and generally turn the first bulb on first.
