Likely the biggest problem with your shifting is the high idle. If your RPMs are not dropping sufficiently you are not going to be able to shift well. Fix that issue first. I use Lucas oil stabilizer in my transmission. Has less fade with heat. There is no reason to double clutch on the way up if everything is in proper condition. Remember: Shift early, pause between gears, and have your idle down slow where it belongs. Even on the way down I almost never double clutch. Not necessary if you use the right timing. Biggest thing is to NOT get in a hurry.
