Hi Shaun,
I have just bought a Epic V10 Sports and have been paddling for the entire month about 2 times per week so a full 8 Sessions (hahah) , so not much expereince at all. I weigh in at 125kg and I'm 195cm or 6ft 4 inch .
Last training session I manged to stay for the longest periods and probably fell off 7 times in a hr session ... pretty proud of myself ... I would highly recommend the Epic V10 Sports very stable compared to the Epic V10 or so I'm told .........
Cheers
Nick
