Based on some of your comments, I really think you'll be happier with the Standard or Roadster. I have a Tiger and had a Rocket Touring. Now, this is blasphemous talk in here, but I'd take the Tiger 7 days a week over the Touring. The Touring just wasn't a comfortable bike to me (ergos were not right for my frame). I can ride my Tiger 100 miles and not so much as twitch in the saddle. I couldn't ride my Touring 50 miles without squirming around looking for another position to relieve neck and shoulder tension. I sold the bike and bought a Thunderbird. The Thunderbird is like my Tiger. I can ride without any discomfort. The reason I think you'll like the Roadster or Standard better is because you say you're used to Dual Sport ergos like the Tiger. The Tiger really isn't a dual sport anymore. Now days it's more like the giraffe of the sport touring bikes. I love the bike; one of my favorites of any I've owned.
Anyway, I'm the same way regarding the riding position. The Thunderbird, while being a cruiser, is *very* comfortable for me. Why do I mention that to you? Because I looked at both the Thunderbird and the Standard Rocket and while I opted for the Thunderbird, I can tell you the riding position on both bikes is very similar. In fact, I'm pretty sure had I bought a Standard Rocket when I bought the Touring (2008), I wouldn't have sold it to buy a Thunderbird last month.
