Don't see a reason why you couldn't just always ride 21mph and 65'. Your wake looked good at that speed. If you enjoy it then do it, and you wont have as hard of falls on your 'old body'. As for the backroll, I see 2 things. 1, you should take a more progressive cut into the wake. Right now you are getting on your edge halfway to the wake and then holding that edge the second half of the way through the wake. You want to be accelerating through the wake but you stopped accelerating halfway through your cut. Build your edge slower and more progressively so that you are gaining speed all the way through the wake, don't hit your max edge till the wake. That will help you with your line control in the air and also take the trick up higher. 2, don't bend your legs quite as much, stand tall throughout your edge in, and up the wake, and you'll land taller. Also lets you take the trick up higher when you come in taller position because you get more line tension at the lip.
Also, you could wait slightly longer to do the trick. If you pause the video when you're riding up the wake you have already started to flip. You don't want to look like you're slipping on a banana peel at the wake. Wait just a hair longer and throw the trick off the top of the wake, not the bottom like you are now. It will help you with the landing by giving you a feeling more like you're falling out of the trick instead of spinning around to land on your board.
Nice job though, keep it up.
