Well, we mainly work with polycarb, in fact we a based out of an acrylics shop so all of our tools (even the drill bits) are designed for plastic. That is the main reason we use it. Also, over time we have found it is very unique, and as i have stated, if you know what your doing, polycarbonate can be used everywhere you use aluminum.

As for testing, we haven't done any technical testing of polycarb vs aluminum...Aluminum would be lighter, but the fact that we don't even have a wielder makes it a lot harder to work with.
