I havent tried one yet, but after last years wreck, which Im still feeling the effects of, I'm definately getting something this year. Was going to go with a HANS, but I'll check out the defNder...even if its a dumb name...and why is it cool to mis-spell stuff...never understood that...ignorance is not cool...and the extreme thing, why is everything extreme now?...theres a home improvement place in town called X-Treme contractors...so thats doubly annoying, exteme and spelled wrong...I dont care how good they are, I'd never hire them because they hit 2 of my pet peeves at the same time!...sorry, STEVE!!! Hey STEVE!!! Im off topic!
