MO-Runner

Have done a search on tires and have only found one person using the Interco TrXus and none using the Interco Super Swamper SSRs. Was thinking of going this route, but am wondering with all the experience on this board, there must be a reason no one is using them. Supposedly they both have siping and good aggressive tread pattern. One other option am thinking about is the MasterCraft Courser CT, which also has the more aggressive pattern with lots of siping. Is there anyone that has used any of these tires, and if so how did they do? Conversely, is there a particular reason that anyone has decided not to try these?
