Your TS jumps should feel poppy, well balanced and well controlled. If your board is going in front of you in the air, if you keep landing on your heelside edge or if you're not getting good pop, then you need to make adjustments to either your body positioning, the way you pop, your cut, or all of this.
I'd focus on these things:
- shift more weight to your front foot than you think is probably right
- keep your back arm bent to keep the handle at your lead hip and pull the majority of the line load with your back arm
- do not bend at the waist, lean down toward the water and away from the boat with your body straight and only your knees slightly bent
- edge progressively - start out slowly and continually build your edge as you approach the wake
- push from the very top of the wake by really standing tall
- last not least: try to edge through the wake straightly, don't try to follow the curve of the wake with your body
If done correctly, your TS jumps will be as big as your HS jumps. Personally, I feel I can take TS jumps even bigger. Don't know why. Maybe because of the "locked in" approach which makes mistakes at the last moment less possible. For instance, my TS Backrolls are bigger and cleaner than my HS Backrolls - and they seem to be easier and even more fun
...but maybe that's just me.
So all in all, good TS jumps are all about good body positioning, correct edging and the right timing (like your HS jumps).
Hope this helps!
