I ended up purchasing a set of 43 stickies. I've got two rides on the SX's. First was the damn locals event at tracy city over memorial day weekend. Second was a trip to Harlan two weeks ago. My initial thoughts on the SX vs Krawler are that the SX's DO NOT hook up on rocks as well compared to the Krawler. With that said, I will see how the SX's do as they get broken in to really judge but out of the box, the Krawlers are far superior on rocks. On the other hand, I've been on two rides and haven't cut a side wall!
The SX's are more expensive but more attainable. The red's are on back order as usual and I think it is only going to get worse with them opening up sales to the general public. Unless BFG steps up their production you will always be on a waiting list and then you will get bumped b/c racers are still going to get priority over general consumer. As it was, certain racers got priority over others, which I understand. I ordered a set of SX's and had them 3 days later or you can drive and pick up a set the same day if it's convenient for you.
