I have a Leatt GPX Trail brace that I recently purchased. Raced MX through the 80's, and never have never used a neck brace. I'm 6' 200#. Used a Shoei off-road helmet. The Leatt works OK on my MX track, but I find in the woods on my HS course it seems to restrictive. It makes it difficult to look up on up-hill sections and while riding standing up. I'm doing GNCC and VCHSS races. I'm wondering what other off-road racers are using as far as a Leatt? The Leatt GPX Race brace looks like it has more room behind the helmet. Watching the 2010 ISDE last night, their braces looked like they were lower in the back as well. Thanks in advance for your help.
