Tri wetsuit - please assist w/purchase

Hello:
I'm looking for your opinions (not trolling). I'm hoping to convince my wife tonight to allow me to get a Tri wetsuit and am wracking my brain at which to get. I've seen some of the threads regarding both of these products, but still need your assistance.

I've got it locked down to the following two due to price and deadline, and a couple of features:

1) Xterra Vengeance Full - Vengeance Fullsuit— Performance and Flexibility (Specs- 5mm, 3mm, 1.5mm Yamamoto #39 rubber/ V-Span Inner body Liner/ Flex-Span arm and shoulder Liner/ Loc Flex Collar/ Hydro Slide Zipper/ Glued & Blind Stitched Seams/ Phase 1 Catch Panel). The Vengeance offers performance and flexibility that are second only to the Vector Pro2. It is designed to perform at or above the level of any other high-end suit for a fraction of the cost. It uses Yamamoto’s #39 rubber on the exterior, which like Nano SCS is very soft and flexible, so the suit is extremely comfortable and provides a very high range of motion. It also uses our exclusive V-Span inside liner throughout the body, and the Flex Span liner in the shoulders and arms just like the Vector Pro2. The Vengeance is available in men’s and women’s specific sizes. Price— $395.

Also, is the 10% discount good for free members of BT, or does the discount apply only to paid members?

Thanks all and happy training!
