Wow, I'm surprised to find that a few of you also prefer to drink from the bottle. I've not had a problem taking the top off while pedaling and taking a drink. Though I've dropped a bottle on a group ride, I've also experienced dropped bottles of others on rides that weren't taking the top off to drink.
I'll have to look into the high-flow camel backs, but I thought that has been out quite awhile. Besides I don't suck. So not sure how that will help.
While puns and innuendo is partly intended, this is a serious question. My son tells me I need to use regular bidons in the proper way and quit embarrassing him. If he only knew! That alone is more motivation to keep doing what I'm doing. <grin>
