I'm new to road bike cycling and bought myself a nice bike, nice shoes and some SPD pedals after deciding I was going to just bite the bullet and learn. Spent a few minutes against a wall practicing and adjusted the spring to make it easier to get out the pedal, especially on the right foot.
Took the bike in my car to a nice quiet industrial circuit and loved the pedals (and the bike), must have done 15 miles on it. Practiced various things and got too confident on the pedals, ended up toppling the bike and scraping the right pedal and hurting my hand a bit. Lesson learnt. I went home, took both springs to the lowest setting and haven't had a problem since. It taught me a lesson really, and that was to be aware. Now I'm out on the roads of an evening I've learnt to be aware of absolutely everything around me for my safety and to avoid panicking on the clipping out bit, which is now nearly second nature. Another month of cycling and it really will be second nature. The benefits, for me, is that pedalling is far easier, I'll never slip off the pedal and I get that feel that I'm 'doing it properley', which, for me, makes me more confident on the bike.
I wouldn't entertain getting clips on the pedals, they always seemed harder for me to get out of if you've got them anything other than 'properley loose'. I considered having pedals that were both cleat in and flat on the other side but honestly? I'll never take the bike anywhere I would be annoyed at having to put my road shoes on. I'll never take it to the shops, for example.
If I want to go to the shops on a bike I'll buy a cheapo mountain bike or old fixed gear.
