Almost all printers can readily handle the 65-67lb range of cardstock. When in doubt, that's the safest bet.
Reading/watching others trials & mistakes is another good leaning tool. Of course, the best will be your own experience.
Can you use too thick? YEP!
It's your printer specs that will tell you if you can handle the 110lb category. You can try and run it through and see how well it works, but If in doubt check with your printers customers service.
110 is a good. and my choice for Art's 18mm quibits. I've had no troubles with 67lb for the 13's. On smaller detailed models such as those MMX sized, 110 is tougher to fold/roll, and looks chunky, whereas the 65-67lb type works, constructs much easier with better looks.
Using a slightly thin cardstock may cut down on the flight life of your model, but that's cheap compared to a new printer.
