The Glaser tools are terrific. They are good for all aspects of woodturning not just roughing. If roughing without sharpening is your goal then the carbide scrapers like the ones from Easy Wood would seam like a good solution for you.
If to much time is spent sharpening, for roughing, then a change to your sharpening procedure might be in order. Put a dry grinder with a 36 or 40 grit wheel next to your lathe with the grinding height at the same level as your turning height. Then sharpening would be much quicker and that coarse sharpen would last longer than the ultra fine edge you are getting from the tormek. Sharpening, for rough turning, should be a quick process. For finish turning a fine edge can save time with the sandpaper. For roughing the surface condition left by the tool is much less important.
I have Glaser V15 tools. I do not feel you would get more than twice the turning life from the V15 over M2 HSS between sharpening. For me the real benefit is in the finish cuts.
