what are you guys talking about? you are all over the place. double clutching????
there is no practical reason to double clutch a 5th gen. if you think so, do more research.
heel and toe is just to avoid shift locking(my favorite drift entry method). you have to be hauling ass to do it correctly and beneficially.
please don't be practicing on the street. and if you are, thats why it seems so hard for you. go to a track, haul ass into a corner, ill bet youll get it everytime if you know the idea and the purpose.
while braking hard into corner, with clutch in, you simply blurp the throttle. you do not ride the throttle. the rpms will rise back up, and when they peak or start to fall you let out the clutch while still braking. then as you cross into the apex, ease off brake, and ease on the throttle just after passing apex.

depends on the car, but sometimes you can do it backwards(use your toe to blurp throttle)
