We used Bosch, because the team welder graduated last year.
It's great stuff to use, you can build a bot in no time, and disassemble it easily... but it adds unneeded weight. You could probabaly use 2 bars of aluminum tube for every 1 Bosch, and still have it weigh less and be just as strong.
But, hey, it worked great for us, so I'm not complaining.
Heh, it'd be sweet if someone built their bot outta polycarb. That'd be rather fragile tho. Just get some nice 3/4" thick polycarb
