Helmets and goggles are all too subjective. What works for one person may not work for the next. Hell, what I thought I liked one season, I didn't like the next. Not to mention sizes between brands don't always fit the same.
That being said...
I'm currently rocking a Motorfist Dominator helmet. I've used it for one season and like it so far. Really like the weight (or lack there of). I've primarily used it with my 509 Aviators and Stage Stunt goggles, along with a Klim Glacier balaclava. Both goggles seemed to seal well. I have some 509 Sinisters I keep for spares as well. Not sure I've even worn them with this helmet yet.
I've previously wore 509, Fox V2, and HJC CL-X4 helmets. The 509 fit a little goofy around the ears, but was tolerable (especially with a balaclava). The Fox was too tight for me in the jaw line. I had the cheek pads sewn flat so I could wear it, but was never super comfortable. The HJC was probably the best fitting helmet I've had, and the Scott goggles I had at the time fit it like a glove.
If you're interested in something, it's always best to try to find it somewhere locally to try it on...or...find a website with a really good return policy.
