Steve, indeed you use whatever works with the pedals your car has. In my Healey it was also more like a "roll" of the foot rather than the heel toe thing. Do what you gotta do to get the job done!

The most difficult thing I've found is being able to maintain hard braking whilst nudging the throttle. Inevitably your braking foot applies less pressure during the throttle part.

On the Formula Fords without power brakes this was a significant problem. Like many race cars they were also non-synchro, so it was a double clutch manuever which compounds the problem of lighter braking during the shift.

By the way:
In 1902 Packard was granted a patent on the H pattern gear shift, which eventually became the industry standard.
