Crowbar,
Sorry to hear you didn't hear from anyone at MogMog. If you'll send me a message off-group I'll forward it to the club president (the guy in Lake Jackson).
I haven't been a paying member of MogMog for three or four years now but do keep a membership in TexMog, up in Dallas, and I'm involved with HotMog (Heart of Texas MOG - no dues, no rules, no officers) here in the Austin region. MogMog membership has dwindled in recent years as people have retired and left Houston, and now their activities seem to be fewer, although I still get a monthly email about meeting up for a noggin and natter at the Mucky Duck (they met up there last Saturday). I usually attend their spring weekend gathering and also the fall regional gathering which is coordinated by one of the three clubs in rotation. This year that event will be in Granbury in early November.
Re: the wind noise -- I've driven a new 5-speeder three times now, up to about 70 mph, and found the wind noise and wind battering significantly less irritating the vintage Morgan 4-wheelers. It's perhaps about like the '36 SS, although truthfully I've never had it much over 65 mph. "Racing" screens allow the air to go past your head (careful while you lean over to say something to your passenger, however), whereas a full windshield causes air to flow at you from behind and from outboard/below (the latter is why wind wings don't work too well on Morgans; the high velocity air is coming over the top of the door toward your ear, entering about 4" back from the front of the door). I guess the worst I've experienced was in a Lotus Super 7 with a full stock windshield. Fantastic fun for about 20 minutes but the battering by the wind was extreme.
I had the same experience as others with a leather flying helmet with the ear flaps -- too much noise -- so I consider it better for keeping my head warm than for anything else. I use foam earplugs on long trips and either a flat cap (shorter bill means it's less likely to be lifted off) or a hard-to-find straw baseball cap in the summer (air flows through it).
