I've been looking at the trick ladder list, am I the only one who find the boomerang in the back is in a (too) early position?
You are probably right. I guess it's in that position because it was a classic trick from the 1960's. I think we could swap it with Dive Bomber, #20. Because we had been using it as a menu, not a ladder, it was not too important the order (except for the different score value).
The list is probably overdue for an update, anyway. Alan Gray made the first list, which I edited a couple of times, replacing some tricks as the state of the art has moved forward (e.g. double wire walker with short circuit). It still has some legacy tricks from the early 2000's while missing some more relevant tricks. As only Texture is register so far, I might still update it, if he doesn't complain.
And can I just register now for the trick list while already registered for the freestyle?
No, if you freestyle, you cannot do the Sport division. But, if there is enough interest, we could have a pro-sport competition, open to everybody. What about one in which we don't count misses and see who can do it in less time? . . .
