Thanks for all of your great suggestions.
a. Looks like I'll be gaining some additional muscle strength throughout the upcoming riding season.
b. I had been considering the luggage rack from the day I got the bike, so I'll probably invest. Anyone have one they'd like to sell? I'll post in the wanted section, wait for a week or so and then buy at full price if I don't get any bites.
c. Don't trust the strap. Got it. Check.
d. I had considered a Sprint, but the deal I got on my new Daytona was too good to pass up, and I ride solo more than with a passenger and think that I'll be happiest with my choice in the long run. Hey, there's room in the garage for one more bike, so maybe I should start looking for something used to fill the gap. I think we'll be fine.
Thanks again!
