I see that I Am Mod clarified the wet/dry thing. Yes, in the US dry means it is coated to withstand some degree of moisture. For ice climbing, a dry rope is fairly essential. I tend to only buy dry ropes, even though they are significantly more expensive. While a double-rope system is much better for leading ice, sometimes I prefer a single on certain ice routes, or when toproping an ice route with a small group (very poor etiquette to toprope ice, but in certain situations in certain areas can sometimes be acceptable).
If you're planning on sport climbing, don't bother with a dry rope. Go for the cheaper, untreated version. Dry ropes do feed a bit more smoothly, but the difference isn't that noticeable. For glacier travel you will want an entirely different cord anyway. You will want something much shorter (60m being far too long), as well as much skinnier. There are ropes specifically marketed as glacier ropes, but most people will simply use half of a set of double or half ropes that has been retired, and chop it to the length they desire.
