I have a touring bike and 2 cross bikes - and ride them all almost exclusively on roads. The cross bikes definitely have a lighter "feel" to them. My Lynskey *is* lighter - but my Surly Cross Check and my touring bike are probably pretty close to the same weight (touring bike might be a little heavier because it has fenders and a rack - but there's not a huge difference). The cross check is not a light bike - but it rides a lot lighter than it is, if that makes sense (and I have boat anchor wheels).
The only real way to tell how they'll feel is to go ride one. If I were starting from scratch with all 3, I would probably just get the Straggler (a cross check with disc brakes). I love my Lynskey, but it was spendy, and I'm not sure it's worth *that* much to me.
Most days in life don't stand out, But life's about those days that will...
