Heel-toe (or toe-toe) doesn't have any influence by itself on whether you'd use Method #1 or #2 since whether or not you double-clutch doesn't have anything to do with whether or not you're braking while trying to execute a downshift. The reasons I said that most people who heel-toe DON'T double-clutch are:
- Heel-toe is executed more frequently on the track where you want things to happen more quickly, so spending extra time on a shift just to avoid a little wear and tear on synchros isn't worth it in that setting, especially since on a track you wouldn't be skipping gears, which means you're already keeping wear and tear on synchros pretty low.
- Most people don't double-clutch at all, whether or not they're on the track or heel-toeing at the same time. I personally only do it when skipping more than one gear, e.g. 6>3, because otherwise it can be tough to impossible to get the shifter through the gate. The ONLY other time I skip gears is occasionally going from 4>6, and I've never felt the need to double-clutch there since the synchros always seem perfectly up to the task. Every other shift I do is between adjacent gears where it's just never seemed worth it to double-clutch. Maybe I would on a gearbox with ratios farther apart, but not on my car.
Understood, what you say makes 100 % sense. We both started speaking about two different things, yet it seems like we met in the middle :-) anyway, thanks for the info
