What's your favourite gear ratio?

My winter commuter is 44x16 with 700x28s. It's about 72GI I think so is fine in all but the worst headwinds and will spin 25mph if you must.

I have another bike that's 48x16, 700x23s and it's noticeably less nippy round town.

I very much like 71/72 GI.

Trying out 44/16.. Some how I dont feel its good for me as i get tired of spinning it..My legs asks for heavier gear..even if I ride breakless..Did around 30+ miles around london..Thinking to get back on 48/16.
