I just got in some 1"/0.065" DOM from speedy metal. I could not test it with a full width since I only have 4’ lengths but it is certainly better than the SS I have. It is hard to say but a 46" span seems to be somewhere near 0.5mm deflection, vs the Stainless at about 1mm. Those numbers are not to be trusted too much but it is stiffer. The cold working really does seem to add a lot to it. On top of that it is extremely consistent 25.45-25.49mm round and smooth. It will certainly need some coating as we talked about in the other thread, paste wax or some other similar non silicon dry coating.
Less than half the price…should I even make a 23.5mm version of the new version? For that price a little wax is no big deal!
