Honestly, I have the worst luck with washes. They never seem to find their way into the seams, and pool all over the place, ruining detail and causing splotchyness.
I know /tg/ hates drybrushing, but I think it's because many players do a Basecoat-Drybrush-details-done system. Myself, I drybrushed the shit out of my first army (mainly because the how-to book said so), but I did so with many hues. For me it went
Primer, Reallydarkbasecoat, Drybrush lowtone (Everywhere), Drybrush midtone (easily reached), Drybrush hightone (Topmost surfaces), Drybrush Highlights (very light).
Though yes, it does look chalky, it was a happy experiment, as I was going for an ash-grey color, and the texture from drybrushing really accented that, while giving the miniatures a grittier look that made them look warn. After a few metallic details and jewling, I was really pleased with the end product. Sure, it wasn't pro, but neither was I. I'm pretty sure that I ended up spending the same amount of time the average "Paint your thins" fatguy does.
Tried recently using other fatguy techniques with some testbed minis... Some parts are better than others, I'm probably going to start abandoning the wash part. Never turns out well, and soap isn't really helping it.
