remember, everything has to be more exaggerated toeside because you are standing sideways. For me, I try to get right on my toes and face the back of the boat. Bring the handle to your butt. When you cut heelside, your handle is in front of you. WHen you cut toeside, your handle should be behind you right? Also remember, a toeside jump requires holding your edge through the wake just like heelside jumps. Do not let up!
You'll get the hang of it! I rode for a almost 2 seasons before I started jumping toeside. My first season I didn't jump. My second season I only jumped heelside. Then I tried toeside and failed miserably. I took a 15 min lesson at a ski school near me... and after that I was toeside jumping. NOW my toeside jumps are actually more consistent than my heelside! I tend to not have a good progressive edge when I jump heelside. Toeside though feels mroe comfortable.
Have fun! It's hard to get at first, but once you get the hang of it... it's an awsome feeling
