[FTC]: Best Tank Treads

Our team is a veteran team, and this is our second year. We were attempting to fabricate wheels to make it up the mountain, but they did not work the best, so we are now trying to find good treads to use instead. What are the best legal treads for climbing the mountain(price isn’t an issue as long as its less than $250)?

I’ve heard good things about Brecoflex but I haven’t used it myself.
