Have yet to master that technique.
Besides, I find it hard to try the heal-toe with size 12 feet and the pedals on the NSX are so close together.

 

heel toe+ double clutch = teh win because heel toe only revs the egnine (but allows you to brake at the same time) and double clutching has already been discussed

 

No need to double clutch on this car. Some cars don't have transmissions that are as smooth as ours and double-clutching can help make it easier to downshift. I heel-toe on almost every downshift before a corner and I used to double clutch on my old car, but there's no reason to do it on this car and it just makes it that much more complex and slower.
