I'm one of those "tough customers"...I hunt, and search, and read-read-read, then talk to others, then search some more.
None of the LDS in my immediate area (So Cal, if you can believe that) had the DUI's to look at or try on - and it happens DUI had a demo days a few hours south of me in San Diego in September.
I went down there, met with the entire cast and crew, and dove three different suits - and realized that I sat firmly between sizes (thanks for the penguin-body genes, Mom & Dad...)
I hustled my way into DEMA and had the folks from DUI measure me. I'm GLAD I did - as I took in the measurements we did at home and it turns out we measured too tightly - as in pulled the tape too tightly around my hips, calfs, arms, etc. DUI did a "loose" measurement.... Again, I'm glad they did.
So I could rent suits during the 7 weeks they needed to build mine, I called their customer service and had them send the hood and undergarmentsa week or so later. Then a few weeks later I wanted to fit Scubaroo's Spring Straps onto my fins...so I called their customer service again and had them ship the rock boots (all shipped next day - no charge...)
The suit arrived the day they said it would. Got it home, tried everything on - it fit perfectly. They were the greatest to work with - returned eMails, took my calls (heck, I would have stopped taking my calls...) and delivered the goods. I couldn't be more pleased.
Although I didn't get a "preview" like your Andy's, I was fortunate enough to get DUI to measure me...I'm glad they did or I'd have to hit the treadmill for sure with the tight measurements I would have given them.
