But neither of the methods you describe is heel-toe, which is the ability to execute a rev-matched downshift (via either of your methods, but usually #2) while ALSO braking.
Thanks for the info and confirmation/explanation. OP did not specify which part of heel&toe exactly is problematic for him, since you already explained the foot work, I just wanted to shed some light on the whole process. Because if he is just learning, he better learns it properly since changing your habits later is much more difficult.
Also, why would heel-toe be usually used with method #2? I toe-toe with method #1 and it works perfectly (in theory, still need to practice a lot :-) ). When using heel&toe/toe&toe, I believe one should always use method #1.
