I am considering purchasing an alternative to the standard cutter head for my Speed-Mat cutter that is designed to cut 8-ply mattes. It cost just a bit less than $500. So, my question is, does anyone who is showing their work in galleries think that it is desirable/preferable to show 8-ply mattes, versus 4-ply? Or, even double matting with two 4-ply mattes? I would like some experienced exhibitors to weigh in. The speed mat is shown below.
