360 (Blind) problems...

Ok, after 3 months of wakeboarding I decided to try my first 360, I choose blind because I can already do the handle pass on a 180 (Blind).

Ok so I go for it, make it all the way around 1st try, but I chunked the handle instead of pass it, of course I didn't land because I went off axis.

Now I've tried probably 10 times now, and I keep going off axis, I can get the handle but it's no good without being on axis for landing, any tips would be appreciated.

Also, I hurt my rear knee on my last attempt sorta jammed it, any advise on how to prevent this type of injury when falling hard? (i.e. Locking knee's bending knee's holding them out of the water when impacting, pushing them in first, ect. ect. ect...

thanks!!!
