Which motorcycle is best for me?

I was looking at bikes like the Honda VFR 800 or the Triumph Sprint ST but I want to know what you guys think. My dad goes on yearly bike trips and they do about 500 miles a day and I would like to go with him without having to quit after one day because I'm too sore. However, I want something with some speed, good handling and a sporty feel. I have a lot of experience riding and I'm comfortable with bikes over 1000cc. I ride a 1983 GL1100 right now but I'm looking for an upgrade. Thanks
