RedstoneLogo Design Contest

A few thoughts and tips -
(1) We like the logotype really clean. So don't want to replace any letters with shapes, etc.
(2) In the logo, let's not try to make something that looks like a roofline, or and "R" or "S"
(3) We are open to logotype-only logo. So I like the idea of keeping the mountains, but if that won't work, we can do logotype only.
(4) Our competitors are groups like Greystar, Asset Living, Cardinal Group Management.

I think we want a horizontal logo. So logo on left, logotype on right. Looking to modernize - perhaps "Redstone" in sentence case with big R and small remaining letters. Do we try serifs to soften it as well? We want to stick with some type of simple mountain logo - don't like things that look like houses, or letters.
