I'm needing some feedback on which cutting blades work well to cut mountable fabric using an FC8000-130. The fabric is PhotoTex Mountable Fabric. I have tried to cut it using the standard CB09UA blade with the blue holder, but the fabric frays and even with two cuts doesn't get cut all the way in some places (mainly corners). Graphtec's support guy has suggested switching to the CB15UA blade or CB15UA-k30 blade, but isn't entirely sure since he hasn't tried it himself, and we's like to see some feedback before randomly ordering things! Thank's in advance for your help!
