I faced the same decision you did this spring. Ultimately, I chose the Explorer. I purchased the "launch" model. This summer I rode it all over Colorado on twisty mountain highways (paved). I also made a trip to the Pacific Ocean and then to Oregon and back. I specifically tried to avoid interstate highways and use the back roads. The bike has been magnificent. No problems with throttle. In fact that's what makes this bike fun. When I loaded up for my cross country trip, I drove to the truck scales and weighed the bike, 2 weeks of gear and me on it. I think it was like 960 pounds. You can accelerate to over 100mph very quickly even going up steep hills in Colorado (although I wouldn't recommend it for money reasons

).
I'm not sure how you can go wrong with Explorer. The only modification I made was to buy a custom made heated, gel motorcycle seat.
Next summer I'm planning on riding to Prudhoe Bay! Wish me luck.
Hope you enjoy yours as well.
