in the future, if Rohr manufactures its our supplies, or registers, it could be interesting to put the � on your symbol, or confusing, I donno. But its something you might want to consider. When the logo appears in black & white for say - a newspaper ad, �^� could be weird. If the logo is reduced for letterhead and faxed, it could appear to be a registration and not a propreitary logo at all. hmm

Is it just me, or does this logo look like it's set in Helvetica? And the R in the circle is more like Akzidenz Grotesk. I'm a bit confused here.

Another way of going at it would be to center name, circle and "R". And by centering, I mean center mathematically along the horizontal axis and then adjust optically.
Then you might wanna print out both versions (Stephen's suggestion and mine) at the same size and look at them from a distance. You'll notice that in Stephen's version the circle will be higher up, but the common baseline will give it a sense of stability and sturdiness, whereas mine will have a more horizontal dynamic. It's your personal preference which will make you go for one version or another, as I think both are valid solutions.

P.S. When you decide to opt for Helvetica for the logo, bear in mind that half the world and their sister's logo is set in Helvetica. Ask Erik Spiekermann (Rhyme & Reason: A Typographic Novel, pages 100-101). I've got a hunch he might be right.

I would make the circle a superellipse, or maybe a lozenge.

Thanks gang...

Tanya: Yeah, I wrestled with the circle-r circle-r quandry. I suppose I could keep the logo pretty big (1"?) and make the registration mark as small as legally possible.

Yves: I might be smoking crack on the Arial-Frutiger thing... either way, they should probably be the same typeface. I definitely want a straight tail. I don't really want to use Helvetica, but I am not terribly happy with how other faces look.

My all-time favorite sans is Interstate but the LC looks like poo. Maybe Champion?

its generally thought that the bigger the logo the smaller the company.

to avoid making them look ma&pop I wouldn't increase it anymore.

Following up on Hrant's suggestion, you could brak the circle up abit and or play around with some different line weights (to differentiate it from a registered mark more).
