I am working on getting my TS dialed too. It is still hit or miss for me...but when I hold position, I can get good pop. When I let the position go..I lose pop...and worse...land on my heels. If you land on the wake...you can save it...but if you are on your heels and take it past the wake at all...you will go out the back.
The key to big pop TS is line tension, and NOT letting your twisted edging position, and the pull across your back arm (right arm if you are reg stance) and thus your strong edge, go at the last instant.
Make sure you can do Kyle Schmidt's TS Pop drill (search YouTube). This will help you master the twisted position.
Once you have that down, a great way to practice is with a short line, and a tad slower speed, so you can do a wake to wake jump that is pretty small. Take a super super short approach....I am talking about edge of the foam...15' or less out! This will force you to edge super late and hard, because you will be edging at the last instant. Try to take it into the flats. You wont be able to if your approach is super short...but this mindset will make you hold your twisted position, and strong edge through the wake. Concentrate on holding that position...all the way into the air...and even till you land. Keep that pull across your body from your back arm.
Again...your goal should be to take it into the flats...which if your approach is short enough....cant happen. If you are at say 55' x 20.5 mph, and take a 15' approach...and actually can take it to the flats... then shorten the approach to 12-13' and try again. You are using a trick to build nervous system/muscle memory into holding that line tension through the wake.
After you get it dialed...lengthen the rope out at bit. Your approach will have to be a little bigger...but not much. You always want to keep the approach very short (relative to a given rope length) so that you feel like you are starting your edge too late to make it.
