between Bontrager Hard Case and All-Condition Armadillo Elite, size 700x28.
Three factors are nearly equally important:
1. Puncture resistance - I commute through some pretty gritty neighbourhoods.
2. Ease of mounting - see #1.
3. Wet traction performance and cornering.
AFAIK, Bonts do not come with Kevlar bead and my current tires do - so I am addicted to easy mounting.
I am very light Athena, working on leaving the ranks, my noble steed is a cyclotank, commute is 30 mi RT at average speed 15-16 mph.
