What you doing, warping them? Or just wearing away?
TBH, I've founf the genuine GM ones pretty indestructable, though after a spanking, I also shift to neutral and put handbrake on, rather than sit on footbrake.
Well that sounds like a pretty insane thing to do. 
If you have been giving the brakes a really good licking to the extent that the discs and pads are really hot then, if you sit with your foot on the footbrakem the pads are (obviously) presing on the face of the disc.
If you are stopped for a few minutes like this then the other 80-odd percent of the disc cools disproportioantely to the area covered by the pad, caliper etc and thus a hot spot is created.
Do this a few times and it is perfectly feasable to warp oterwise good discs.
And cook pads.....
Ha ha, I thought he meant to help him slow down!! 
I think the handbrakes on both my Omegas wouldn't slow a pushbike down, useless bloody things

Aye. Right.....

Quite correct. They are parking brakes, not handbrakes. i.e. apply whilst stopped, not as an alternate means to retard the vehicle whilst at speed.....
That said, always worth applying the hand/parking brake regularly, sometimes whilst carrying a few miles per hour, to remove rust. Use it or loose it.....
