So, maybe in the end, the bike and "paraphernalia" weights of my bike and the rental were the same after all. (For the record, I will be using water bottles when the heat turns up a bit in Austin and I am doing longer rides.)
Maybe part of what made you ride better in Hawaii is that you weren't dehydrated. You should drink water even when it is cool out since you are still sweating and releasing water in your breath... It just doesn't make you thirsty. Or so I have heard.
In fact, I think at the extremes, climate-wise, cold air is often drier than hot air.
