Ok, the multi-tec...if I didn't like coffee so much I'd be wearing my corsair most of the time! I'm still thinking about buying a new corsair someday, mine is too old to wear now really, a nearly weightless helmet to me.
The Multitec is a good helmet though, just seems a little heavy to me. But at least I can see where the gas is going at the pump when I can flip it up
I wear specs too so the flip up is nice for those.
The HARD seems delicate but as long as you take care of it, no problema. I've had mine for years now. I velcro the 'box' to the right side of the helmet near the bottom and the wires run into the helmet easy like.
It is very bright at night. I tuck mine in so I can barely see it, the LED will light up your entire faceshield and is blinding. Easy to take care of that via positioning of the LED.
I like the visual, can't trust these ears much anymore.
One thing...DON'T forget to shut the on-off switch off or you'll waste your batt's. Check it before you store it (don't ask) also, just in case you 'bump' it on again. The CR2302's ain't real cheep (can get 2 for 5 bucks in some places I think but they are usually more expensive than that).
Biggest thing is, the unit is not waterproof whatsoever (but neither is my escort). So don't speed in the cold rain without your RD. I was lucky enough to be let go that time doing go-to-jail speeds trying to find some heat, lucky for me the LEO was a sympathetic biker!
For reference, until I crashed last Oct, I hadn't owned a cage since Jan 06. I ride daily and typically about 1000 miles/week, about 50k/year. My RD/HARD is on the KS for all trips outside the city.
