Double clutching and heel-toe?

its not going to burn your clutch if the clutch is fully in. single clutch revmatch is exactly the same as heel and toe except your not braking, unless you are double clutch heel and toeing.

Not needed 100%, because you can get into 2nd at 60km/h from 4th without double clutching. Of course there will be a bit of wear on your synchros. But say you were going from 2000rpm in 6th gear and wanting to downshift to 2nd gear at 80km/h, then double clutching lets you go from 6th straight into 2nd while minimising wear on the synchros.

You don't need to double clutch as your gearbox will let you do it. Just saves on a bit of wear.

well what I do is use double clutching to downshift on straights when i need to accelerate like overtake or something and heel-toe for corners and sometimes coming to a stop.

If you were downshifting from 4th to 2nd, blipping the throttle matches the flywheel speed (engine side) to the clutch speed (gearbox or road side) so that you don't burn the clutch. If you just release the clutch pedal so that the engine speeds up on its own, then that duration where the clutch is pressed down partially causes wear (burning) on the clutch.

You will have more wear/stress on the driveline NOT blipping the throttle. Thats the point of blipping, to rev match the next lower gear.

Ah right, I forgot that on OzHonda VTEC means "more speed".

don't take your foot off the gas pedal. clutch in and downshift to second! your revs will fly up as soon as you clutch in...clutch out and floor it!

Isn't that gonna damage your gearbox or clutch? its bad practice to be on the throttle while letting the clutch out, also your going to damage the synchros since revs wont be matched
