Thanks to all who commented. I won't quote everyone's reponses, but I will try to comment on several that struck nerves.
I must say in all fairness that my friends weren't trying to lose me. In fact, we all look out for each other and we stay together when riding. It was just the acceleration when merging into traffic that left me behind. We maintained 80-90 mph the whole way and there was no problem for me. I am very comfortable at those speeds, and I'm smart enough to know when to slow it down for safety, not to mention LEO's. No weaving in between cars a la crotch rocket riders, or as I like to call them "rocket scientists."
As far as having too much power, I disagree that our LT could ever have too much power. If one has more power, that engine doesn't have to struggle and rev to the stratosphere to get the job done. IOW, less drama. I personally like hp and try to use it judiciously. Having driven AMG Mercedes on the Homestead Speedway many times, I can appreciate the difference more hp can make on the same type of vehicle. For instance, a regular SL500 is a wonderful toy; an SL 65 AMG with twin turbo V-12 is a blast! One doesn't have to use all 600 hp, but it's great to know it's there. I have a CL 63 (500-plus hp) on order to satisfy that desire.
Finally, I truly don't have anything to prove to myself or anyone else. Going fast or reaching a certain level of g-force on acceleration is a pleasant experience for me, as is the challenge of reigning in that power and controlling it, so that it is artful, graceful and exciting without the drama. That's what I try to do on the track and that's what I like to experience on the bike on a personal level. Thanks again for all your comments.
And, by the way, met a pretty new nurse at work today, who rides! Testosterone level back to normal.
