My first two helmets were Troxels, and I loved my time with both of them. The first was a Troxel Capriole, back over 10 years ago. It did its job, and then I outgrew it. Back when I was in high school I rode in a Troxel (don't remember the variety) and never had any troubles with it. It was not low profile in the slightest, but I don't know of any helmets that were at the time. Personally, I preferred a decent helmet to finding one that was as low profile as possible. I replaced it during my first year of college with an Ovation schooling helmet. Loved it. A friend of mine replaced hers with another Troxel. We both needed new helmets this year (apparently we're on a similar schedule, lol), and she bought an Ovation schooling helmet identical to mine. Tried it on, hated it, and I bought it from her. She got another Troxel.
Moral of that story? Try on the helmet you intend to buy if at all possible.
