I got the impression that they are not pushing that much on the lower levels, which is good. I can hardly do any trick on level 4, but they feel like a good challenge, however I want to try the basecup hanging fast hand spike (5-7) which is similar to something I have landed.
In general I think that this trick lists are maturing now after three years into a more exponential difficulty towards the higher levels, which I think is a great evolution.
