Team 535 also followed the rules as to tether. We had a pair of assemblies where we spooled out a 22 foot long by 7 inch wide piece of lexan. We could score in both zones while having our bot on the field. We called tham the tongue and tail (TnT for short). The two assemblied weighed a total of 22 pounds. The first thing we considered was a tape measure but we decided it would be an entanglement risk. We could have found a better use for that 22 pounds if the tether rule was as lax, in the beginning, as it was toward the end of the season.
Another pet peeve I have with this years game is changing the rules from qualification rounds to the final rounds. The elims required strategy, the finals, for the most part, required battlebots. IMHO the rules should have stayed the same.
Just my $.02 worth
