Well...I used to troll the Shadow forums, so I have, at least, a passing familiarity with the the 1100. I also had the opportunity to throw a leg over an older 1100 ACE. After the Vulcan, it felt a bit small. I've also read that the 1100 wasn't exactly a powerhouse, and you could probably expect similar performance from a newer 750 Shadow.
I'd hit Hondashadow.net and see what you can drudge up. I don't want to point a finger and say, "nope, that bike is weak" since I don't know a whole lot about it. I DO know a VN900 will hang all day with an 1100 V-Star, and be more comfortable doing it.
