IMO, the Shelly's section since the flood has gotten harder. There are a couple of bigger drops then beforw at the beginning, the boulder garden has more difficult lines, and the drop after the garden is much bigger. Shelly's rapid changed with the flood to be a straight, no real lateral last year. However, this year they must of added rock or a rock moved on the left as that lateral is back. The entrance above Shelly's is also more exciting.
It seems like there is some new constrictions/bank work in places to deepen the channel below apple valley bridge which is great and it seems like there may be a couple new drops created? The playpark has also been updated with new features and the big drop in town before the confluence is gone.
