I've changed from flat bars to bull horns. I never used the bottom position of the drops, just carried an extra foot of tubing around for no apparent reason. I think all of your comments regarding the advice you've received are right on. You do get used to the neck issues, and having options for hand positions greatly reduces numbness in the hands. Getting a bit more weight on the front wheel offers much more control, and you can absorb bumps with your arms and legs more so than your spine. It doesn't require getting into a full tuck. There's a very happy medium to be had.
