I really don't want to start a urinating match here but I'm looking for input on one specific feature. I'm not a fan boy of anything I can think of (other than Subaru and Snap-On) as long as it works as expected. I'm familiar with the tech data of both the 64" FC8600 and the S2-Tangential series. I understand one may or may not be better at cutting thicker materials, reading registration marks, fine detail, tracking ultra long distances and so on. My main concern at the moment is solely perf cutting, or flex cutting, or thru cutting or whatever the word of the day is. It seems to me, in my mind, that the FC8600 with its separate channel that it uses for perf cutting would do a better job in that particular area. From my understanding the Summa flex cut works similar to the roland system which at the end of the day digs into the cutting strip, which in turn wears the blades and strip out much faster. Do I have this right? I mean, my Roland can perf cut but I don't believe it was built with that in mind. I will say it has read all 5 bajillion registration marks I've ran through it so there's that. Does anyone have anything on this?
