Would a touring bike be better for my purposes?
I currently ride a hybrid (mid 1990s Giant Nutra), which works well enough for my predominantly utility riding but I do get frustrated at how slow I am on it--I just don't feel particularly efficient because of the riding position and the weight of the bike. Also, I sometimes haul decent-sized loads (groceries etc.) and the only rack I can use on this bike is a seatpost-mounted one that significantly affects the handling in a bad way when it's loaded. Then I was trying (not successfully) to help my roommate find a bike on Craigslist and saw a couple of very nice touring bikes for sale at excellent prices, and got to wondering whether I should look into getting one at some point (unfortunately the ones I saw on Craigslist were almost definitely too big for me). Would there be a significant difference as far as efficiency in riding around town and carrying stuff with a touring bike as opposed to the hybrid?
