In recent years I've had a couple of ST1100s, a GL1800, a Wee Strom, a CTX700D, and an Electraglide. I currently have a 2013 Trophy in addition to the CTX1300.
The STs were great in the twisties. But they moved around a lot in the wind on the open road. I did not really feel comfortable with the forward lean of the seating position on the highway.
I traded one of the STs for a Gold Wing. It was really nice on the highway. It did not get around the twisties as well as the STs. The Gold Wing moved around a little bit when I passed the trucks. It was very comfortable. I really liked the cruise control on the highway. The Gold Wing was bigger than I really wanted for solo riding. I would still be riding it today, but it was killed by a deer.
I traded the other ST for a Wee Strom. It was not set up for highway riding, but it handled very well around the trucks. It had no wind protection, so I didn't ride it a lot on the highway. Suzuki closed down all of the local dealers during the bankruptcy, so I traded it for a Triumph Trophy.
The Trophy has the most comfortable riding position of any bike I've ever owned. It is very good in the wind, but it blows around quite a bit more than the CTX1300. It wiggles around a lot on wet surfaces due to the tread pattern of the Pirelli tires. The back tire is slick down the middle. The Trophy has the best fairing and windshield of any bike I've ever owned. It's great in the twisties, but still has a nice upright seating position for taking in the sights. If this bike had been more reliable, I would not have bought another big bike. When it runs it's the best bike I've ever ridden. But it sometimes chooses not to run.
When my Dad died I got his Electraglide. I never was comfortable with that bike. It shook and vibrated and made too much noise. It was way too heavy and way too hot. It was like driving something straight out of the 1950s. I sold it to a friend who loves Harley Davidson. He thinks it's the greatest thing he's ever owned. The Electraglide was the only bike I ever owned that had properly working self cancelling turn signals. The CTX, the Gold Wing, and the Trophy all suck at cancelling turn signals at the right time.
I bought a CTX700D last year. I really enjoyed playing around with the DCT. I never did get the wind protection sorted out to suit me. It was pretty nice on the highway. But it turns out that I am more comfortable on bigger bikes. I had the CTX700 for less than a year before I traded it for the CTX1300.
The CTX1300 may turn out to be the best highway bike I've ever owned. It ignores cross winds and trucks. I can just sit there and take in the sights comfortably. I hope adding a taller windshield does not ruin that.
