How is your skills now?
I'm a bigger man than you - 6.3ft and 264.5lbs. I've bought 1.5 week ago first EUC - V10F, so we made similar decision.
Don't give up man! I have big problems with my riding but I'm fighting. I know that you wrote this post at March, so probably you're riding very well now. I've just started. Couple years before I was very active person and had about 44lbs less then now. In last years my physical activity was piece of nothing. Now I know that I must make my legs stronger and work about balancing. I have similar problem - too low speed. I put 40 PSI to my tire and I'm just thinking which pad sensitivity choose, default was 100%, now I'm trying to 0 and default angle of pads +3 degree.
Someone needs really 30minutes and other people weeks of hard works - it's nothing bad. I think the demons that I'm fighting with are smaller everyday. Of course - I have some "bad days" (like today) where I feel like "I can't", but the rest between trainings is very important too. This evening I go to train very frustrated and this wasn't a good idea. I don't myself hurt because I try to protect myself but this could be issue too - Too many jump out from a wheel, probably if I longer stay on the EUC - the learning will be shorter. I don't give a F about scratches but a little to much give a F about my health.
