Oh really? lost a drive chain on an 8motor swerve to one of the modules recently and kept on driving just fine, barely noticed...

One of the largest Pro's to swerve is almost never having to get into pushing contest you don't want to, in many cases rendering 2 speeds not necessary. (keep in mind i had a 2 speed swerve in 08, using COTS AM gen2's....so the 2 speed part really didn't require much work on my end)

Only effective if you have a good driver who can capitalize on the directional freedom that a swerve offers.
I've got a few concepts that could hit < 35lbs for complete chassis with completely independent module power and steering, so weights only really an issue if you aren't trying hard enough

Please only post things when you KNOW them, preferably from experience, or as some have done, put a proper disclaimer
