i sidehop like like but to the left/left foot forward, my biggest issue was not with the padal catching but missing he front wheel onto the wall, this was because i was thinking about my foot, i have got over the issue now though and never miss, which i'm glad about because it hurts and i look like a twat (eh ash). I don't know what i can sidehop just that i did my biggest yerterday:) so my advise would be just to practise the way you feel comfortable, then when you have reached 40+ one way start having a go the other way. hope thats helped
