I normally subscribe to the " bigger bike more power" theory but in your case I don't think it would be wise. I assume that the experience you mentioned was your total of all motorcycling? No long history of dirt bikes or other 2 wheeled toys? I gotta give you credit for approaching this logically and asking advise of others. Many men wouldn't do it. You're a smart guy.
The reason I questioned your total back ground is that folks with off road riding have the benefit of motorcycle control experience under a huge variety of conditions. Not that it has squat to do with traffic laws or defensive riding on the street but the "bike handling" part is good. Rather than pedal any more advise your way how about taking a look at the questions below and honestly answer them for yourself. I'd be interested know how you feel about their relevance to your situation.
1) Excluding external threats from traffic and the like, are you as comfortable operating your current motorcycle as your automobile?
2) Do you ever find yourself spending too much time "thinking" about what should be second nature with respect to riding your bike? Don't forget question 1. A yes on the first question should be a no here.
3) Can you aggressively counter steer to avoid objects in the road?
4) Are you comfortable using the front brake with more authority than the rear?
5) Do your feet come off the pegs just before you come to a final stop at a light? Do they go back on the pegs as soon as forward motion starts?
6) Can you ride you bike at a slow walking speed, feet up and make a u-turn?
7) Can you lean your bike comfortably in turns? Look at your back tire to see how far you've been.
8) Last but not least...have you scared YOURSELF lately? I don't mean some fool trying to ruin your day. I'm talking self imposed fear.
There isn't a day that goes by while riding that I don't see someone riding around with the wrong answers to these basic questions. Just so happens most of the people you see on the road exhibiting the wrong traits are riding big 800 lb bikes. Big bikes are not a very good tool when your early in your learning curve. Just figure out where you are in your learning curve and buy accordingly. You should never be uncomfortable handling the bike your riding. Never. There are so many outstanding bikes on the market today that aren't quite as massive and intimidating as the LT. Heck for the price of a new LT you could buy 2 bikes.
