I love when Simon asks for opinions on gear. And so casual, too...
I wear Profilers, because the lens cleans up quickly, the lens is easier to change than about anything (except for an unusually ugly JT rec mask), and you can get the odd bounce off the snout.
You could get the bounce from proflex too, but without that rigid jawline part, it smacks your mouth harder.
JTs are hands down the best looking goggle. I am not sure if it is because of being used to it for so long, but the look is less... contrived? It looks like the grill is a paintball mask, not a paintball mask from a sci-fi movie. The biggest problem with the JTs is that the foam is soft and not durable. It soaks up sweat for like one game then that sweat gets squeezed onto your face for the rest of the day. Being so soft, the googles move around on my head a lot. Also, the soft ear protectors don't attach well. In all, the proflex is like a lot of little parts that added up over time to make an old school mask into something modern. The dumb thing is that with the new designs out of JT, they are making their mask look like a Dye mask. This is super stupid- 1, the JT look was developed over a long time and is instantly recognizable; and 2, moving toward one of your competitors in look is like admitting they were right all along. If JT wants to change things, they should scrap the modular design and make a mask with the same look as the Proflex (or spectra, flex7, ice) that is more integrated in construction. Also, that crappy foam's gotta go.
The Dye mask looks smaller on the head, whcich is great if you don't have a huge head. Big fat guys with little Dye masks crack me up, because there is this double chin sticking out the bottom. OK, I don't really laugh to their faces, but still. The foam in these masks in what everyone should be going for, IMO. Invisions don't move around on my head, and I love that. The multi-directional grill-pices are stupid looking, though. It is like the "mask of the future" from 1995. The lenses are an ordeal to change out, too. They aren't as easy to clean as Profilers, either, since fill and shell fragments work into the frame of the goggle.
I kinda feel that JT's design ethos is construction gear, dirty, tough but durable looking stuff. Dye seems to go toward the space age, futuristic, ninja paintball thing.
Vforce has ok foam, a great lens system, and the face is almost as bouncy as JT Proflex. At the same time, shots from behind and to the side can get inside the goggles, the head is kinda large, and I feel that the sides are too rigid. It would be cool if they folded up in the kit bag like Proflex goggles. I wish the foam were a little more firm, and the whole assembly a little smaller. The look is less silly than Dye, but it has a little bit of this cheesy space skeleton thing.
Best Look: JT
Best Foam: Dye
Best Lens: Vforce
Most convenient to pack: JT
Smallest profile: Dye
Bounciest: JT
The Profiler has the distinction of being second best in most of the above categories.
