Persoanlly I think H$N devices should be your decison, in vintage I see alot of roll cages that are a joke, hardly any side bars, drivers sitting too high for their given roll cage. I'm old school I guess, I fiquire I'm taking chance when I get into race car, and I'm OK with that. I think heart attacks problaby kill more vintage racers than anyhting else, lots of AARP members out there.
Issac is working on a good HN device, they have a good design already, but are working a low cost unit, I'm talking like a 100 bucks. Not many of the HN devices do much for lateral hits. The problem is that alot of grups are only honoring SFI specs, and SFI is governed by it's exclusive members, meaning the very folks that sell this stuff, so if you and I come with better patented idea, the curerent SFI member will shut us down by not allowing us to get SFI rating, ti all a joke, they are trying to make amatur racers feel this stuff isn't dangourous, guess what it is, and you can killed doing this just like you can in your street car, probably easier in your street car. Everytime I get on a airplane after being on flight that almost went down many years ago, I tell myself, i could die doing this, but I takethe chance to go and see the palces I wont to, I think the same way in a race car, I have no illusions this is totally safe sport and that a HN will be my savior, I'm willing to take the risk to do what I love.
The groups are going to price us ouf racing before it's over, and following the idiots that run SCCA (nothing more than a bunch of church deacons), far form professionals with real knowledge is kinda funny. The whole deal on the belts was nothing more tha to sell more belts there was no evidence tha proves our belt were falling apart, just the SFI members wanting to sell more belts. I see it this way, you want to wear a HN device more power to you, but don't fool yourself that it will save you though, racers have died from head neck injuries wearing them, so while it may increase your chances, great, just be assured, you can still get kiiled doing this, and ask yourself are you OK with that, for me the answer has always been yes.
