What's your favourite gear ratio?

My bike currently has a rear sprocket of 18 teeth and a front chain wheel with 48 teeth and 700C wheels so I think that makes the gear around 70 inches. I find it a bit too low for my liking but it gets me up hills. I think I would prefer about an 85 inch gear and walk up hills.

How much have you ridden with 70GI?

If you ride enough you'll adapt and be able to spin quicker, stay fresh and beast those hills you'd be walking. No bad thing at all.

I ride 52/15, anything less would be too frustrating, I guess it depends on the type of person you are, If you're the type of person who doesn't mind waiting a couple of seconds for a web page to load; go with something like 42/15 but if you've thrown your smart phone against a wall because it took too seconds too long to access your email; go with something with a little torque!

OMG you sound really cool !!!
