Im going to have to agree with tim 100% on this one. Ray hasn't advanced his elementary designs at all in years, which i find very hard to justify. Of all people, he should recognize weight and bulk saved by reducing quilt size and adding features to make them more efficient. Its not terribly difficult to make a good footbox either. A 3D box whether square, circle, diamond, drawstring+stopper, or oval is a more comfortable, more weight efficient option than a taco-fold at a small added level of difficulty. Just because something works, doesnt mean it couldnt work better.
1.1 is a good fabric, but there are great benefits to momentum at a cost. I think Ray started using Climashield XP now, which is the best synthetic quilt insulation available. He keeps the change low key though, so people dont question his love of 3D or try to debate clo vs inches of loft as a measuring tool. He also doesn't reveal his weight of XP making comparisons difficult, although its probably around 3 oz/yd
I wouldn't consider calling the taco-fold 'crap' being too harsh either, even from the competitive perspective of Tim. I would call them competitors, but on completely opposite ends of the spectrum. hating on tim when hes not even pushing his products is a little nitpicky.
Ray has done alot for MYOG, but that doesnt protect his stuff from constructive criticism. Remember that corn flour soup stuff? His quilts are a decent product, but are very far from optimal if you are concerned with weight, performance, and bulk. Topbags on the other hand...
