The jumps were all dirt when I went. I think they had plans to do something with them.
I reckon you should try a wider and higher profile foam in the Dboots if you are suffering with sidebite
Mr 'O' Racing make some great ones
If it's wet I'd start with Ballisitics, if it's dry start with Schumacher Mini Spikes in Yellow compound. Ballistics in the dry dont give much grip as the spikes move about too much in my opinion and the flatter profile gives little sidebite.
