QDM,
I'm thinking the Alpha may be a bit overkill (which is ironic in itself, but I couldn't think of a better word) if you're only going to be using them in a Cub. As a mate of mine says, a Cub carries just enough energy to barely kill you.
Obviously headroom in the Cub usually isn't a problem, but I seem to remember the Alpha being extremely expensive for what it was. I and most of the aerobatic pilots I know that wear helmets use the HGU-55. Get it from the States at current exchange rates and you can do very well. They're a good helmet (good enough for NATO fighter jocks is good enough for me) and they're lightweight. Given your application and how much you're going to be wearing it, I think the light weight, slimmer profile, and reduced cost of the HGU-55 would make it a better choice.
But that's just my .02 worth.
Thanks a lot. I thought the alpha was lighter and smaller than the HGU-55, but will check it out.
I don't think I'm that likely to crash, but equally I am starting to approach nearer to the limits of what the machine can achieve than I used to and that obviously increases the risk of a misjudgement.
The SC is very uncrashworthy, in my opinion, and quite a few of the US pilots wear helmets and swear by them. One of the prime Alaskan safety mods is to put an extra brace in the roof as the cockpit area has a habit of concertinaing together in a crash. Any kind of deforming impact in a Super Cub will undoubtedly result in major head injury without a helmet. Equally, however, the seat backs are very low and there will be enormous momentum imparted to the head round a fulcrum at the shoulder blades, so a heavy helmet will increase the already major risk of cervical spine injury.
I am certainly not over-anxious, merely a pragmatist.
