I can assist on this as well as my shadow is Anovos and I've done another Anovos stormtrooper as well (and have 1 in a box still for a clean I'm doing, don't tell my gf).
Where are you having the most issues with the size at? You may want to try it with the undersuit on and see how it looks too as that'll fill it out a bit. I don't think you'll ever get quite to the "tight" that you are looking for but everything is fixable and adjustable if you are using E6000 glue ?
By the way I'm like 6' 2" and 150 pounds as well, so I know the feeling.
