Ben, I gotta ask. Why the personal crusade with the helmets? I'm sincere when I say that I get it, but it comes down to personal choice, right? Are you just trolling or is there a story there somewhere?
Xavier, if you check out Ben's profile, he's got 3,000+ contributions. Un-trollish, esp as he's contributed stacks of routes to the database, a step seldom taken by those who live under bridges. You'll notice that every fifth comment is helmet-related, and as you say, it's a gettable point being made. Irony here: my first thought when I saw this photo way back when I was green as grass to Red Rock was: "wow, Tom and Brian are climbing some rad-looking shit! Can't wait to do that one! No helmets though? What a coupla knuckleheads..."
You simply can't account for the vast gulf in personal taste and style. I wear mine because it seems much more likely that I'm going to live long enough to best Wilt Chaimberlain in at least one area if I do. Plus, peeing kidney-filtered PBR on the graves of those less posessed of forethought is an old Irish tradition. Or maybe it was whiskey. As Q-Tip said, "If you're hitting them skins, better wrap it up tight!" Words to live by. Coming from the ground falls-are-rad school, it makes the odds better that I'll live to assert than another top roping spradboy is a candidate for the musical theater all-star team.
