PolyCarbonate / Lexan Build Platform Pro's Con's

I had been printing on Lexan (3.0mm) also from Lowes for a couple of months, I'm back to glass right now. 

Pros for Lexan;

Parts, ABS and PLA stick really well, really really well.
Take the Lexan off the head bed and bend it, parts pop off
Cools off quicker, doesn't burn hand like glass
90c ABS printing, bed heats up to 90c fast, (110c for glass, very slow for the last 10c)

Cons for Lexan;

Get's etched by the parts, the patterns start showing up in later prints, not a biggie
Parts stick really well, eventually found that removing the lexan and bending it to pop them off.
Many binder clips required to keep Lexan flat on heated bed, need to remember to drop Z before homing XY
Lexan eventually won't be flat, and thus print bed isn't level anymore, get new Lexan.

Glass lasts forever if you don't break it, but the Lexan isn't that expensive, and I can cut their default 8x10 sheet with a saw, glass I need them to cut.... ever seen a 16 year old try and cut glass at Lowes.... oh dear.
