Comfort: Which Rolex "disappears" on the wrist?

[Eric88]

I'm looking to add a Rolex in 2011 that will disappear on my wrist. I love my Sub-C, but it is fairly chunky and I would like an alternative to change it up from time to time.

I'm thinking about a few different watches, like the Explorer I (pre-2010 style), the Explorer II (perhaps white dial) and the brand new Explorer. Each of these seem low-profile and quite a bit lighter than the Sub. I know a lot less about the DJ and other variations with Jubilee bracelets, so I'm open to any suggestions for a no-nonsence comfortable Rolex. I'm not much for gold or TT, so basic SS will do.

Thanks in advance for any recommendations.
