Both years we have had a shifter with quite a bit of power, last year we shredded I believe 6-8 belts total mostly on the wire mesh area. In low it will spin them even up against a wall so there is a bunch of stress.
We found that it wasn't worth it for us to go with the solid core center since our tracks always ripped first at the edge inward. At the price of the solid centers you literally get twice as many with the serrated center. I have seen a bunch of new pneumatic tires that can easily provide the same amount of traction as the supergrip belts. I can bet that we will be a wheeled bot next year, probably 6 wheels that are 3-4" wide 6" diameter pneumatic. Also keep in mind the delivery on the Brecoflex is pretty terrible, usually at least 2 weeks and up to 4-5 sometimes.
If I was going to use them again I would look at the Gum Rubber and Red belt self centering.

If we where going to be around next year we would probily have a design simmilar to team 25's. 6 wheels like that.

The shipping we have never had a problem with tho. Always recive them within two weeks

Its listed somewhere in this thread. They're green-blue, probably the same ones matt mentioned. They costed us $200 a piece. Another reason why belts have a tendency to rip is the tension on them. You really need to find your happy medium with them. If theyre too tight theyll rip and youll lose traction. If theyre too loose theyre can bind or crease/rip and youll loose traction. You gotta find the happy medium with them.
