I own three suits ...
- DUI TLS350 Signature (custom cut)
- DUI CLX450 Signature (custom cut)
- White's Fusion (size XXL standard)
I've put hundreds of dives on the former two suits, and about 40 dives on the Fusion. Of the three, my preferred suit is the TLS350, which is what I dive the most often.
Likes ...
- TLS350 ... it's comfortable, easy to get into and out of, lightweight, dries quickly, and simple to maintain
- CLX450 ... it's durable
- Fusion ... it's flexible and very lightweight for travel
Dislikes ...
- TLS350 ... haven't found much to dislike. It tends to get leaky from time to time, and I find and fix the leak (DUI stands for Dry Until Immersed).
- CLX450 ... it's heavy and less flexible than the other two suits
- Fusion ... it's a pain getting it on and off ... and it doesn't really fit me as well as advertised. I'm a fairly hefty guy, and while they promote the "oversized bag" and stretchiness of the outer skin, they made the forearms and calves area for skinny people, so it binds in those areas. I can get by with a thinner undergarment to compensate, but I typically dive in very cold (low 40's to mid 50's) water. My impression is that this suit isn't made for large people, no matter how it stretches.
I use the CLX450 for teaching, because of its durability. I use the Fusion for diving in warmer water where I can get away with just a MK2 undie and a thin base layer underneath it. I use the TLS350 for everything else.
Also ... I own several undergarments, and prefer a Weezle Extreme for diving in Puget Sound. The Fusion isn't compatible with that undergarment because of the Weezle's bulk ... and because the Weezle requires loft for warmth and the design of the Fusion is such that it keeps wanting to squeeze all the loft out of the undergarment.
So the answer to your question is really going to depend on a bunch of things ...
- your body shape
- what temperature water you're planning to dive it in
- what type undergarment you're going to use
Also, it's going to matter whether you want pockets you can use or not. The outer shell of the Fusion makes pockets problematic. Some users have figured out a way to attach velcro to their suit to "fix" the problem ... but unless you're into DIY solutions, with the Fusion you're going to have to accept a bit of "sag" when you put stuff in your pockets.
The one place where I think the Fusion will become my "favorite" is in the Florida caves ... where the water's pretty warm and a streamlined suit will provide a lot of benefit. I'll find out in August, when I go down there for my cave training.
Oh ... and if you're thinking to order a pee valve, don't get the stock White's one. It's just a small Sytek dump valve with a flexible hose attached ... no balanced check valve, no quick disconnect ... and it's way more expensive than better products like the Halcyon or Salvo valve. Skip the "factory installation" and have someone aftermarket install one for you.
