If it's rubber, count me out. I do have a 4300 though.

Honestly, I would be running at marcca more often if there were people running foam. I can't see myself gluing up Sorex tires every few weeks any more to compete with the fastest guys, and I haven't seen anybody making the Take Offs work reliably. Running foam would be so much cheaper but no one seems to want to listen.

So, oh well...
