My commute is 9km and I wear bibs mostly because I've never found a saddle that I could ride on for 30 minutes each way, 5 days a week without some sores developing. No issues with bibs though.
Also coz cat6
Lidl memory foam saddle cover for about £4 has made my saddle very comfy. Might throw 2 or 3 more on it though as its got to carry me from London to Paris next month
Unrelated, on my old bike I used to ride in the lowest gear only so that I wouldn't arrive sweaty, it was 39/25 or whatever and about 5km. Any downhill you have to coast, on the flat/hills you're limited to a certain speed by cadence. Only way to stop myself sprinting everywhere
