Hey Justin,
YES!! - that's great board size! - having sail sizes 5,3 and smaller and the 77 liters will make it a lot easier for you to rotate!
Do the movements aggressively and you will usually make it landing on your back on the first day!
Don't take too big waves... a small 30-50cm chop is enough.. otherwise you go too high and rotate too much end over end, no control,... for the beginning take a small ramp!
Please let us all know about your learning process!!
Remember, it is actually easy, GO FOR IT!
good luck!
Rossi
