Well, my replacement M1300 (for my M2500) screen fabric arrived today rolled on a core.
After placing my order with the dealer, I followed up about a week later with a phone call to Draper to request that the M1300 be rolled on the tube (which they call a core.)
The M1300 will come folded UNLESS you follow up with Draper to request the rolled on the core method of shipment.
I will post in a few days my observations on the differences between the two materials (M1300 and M2500.) I am hoping to gain some increased sharpness and more uniform white field with less color splotches (not caused by dust), and definitely want to NOT see the screen fabric material during the light/white screnes.
By the way, Draper recommends snapping the four corners first, and then proceeding with the rest of the snaps. It works.
