I’m a fellow Camino Commute (with G-ones and a 42T front ring), personally I think it’s a great year rounder and takes all the punishment of hopping kerbs, gravel tracks etc. I think the key for a quick commute is keep as much at the office as possible and on the days I’m loaded up with stuff I really notice the difference.
I’m lucky enough to have showers and lockers at work, so I use a bar bag and rucksack for my laptop, lunch and tshirt for the day – I then keep my lock, shoes, trousers, wash stuff and a towel at work. It’s then just a case of remembering to take in clean towels and clothes as required.
If I’m in the office two days in a row I just leave my laptop and rucksack at work and just use the bar bag, laughing all the way home.
