SPD's here (for now) and I had a lot of problems learning. DH finally adjusted the tension on them to real loose and I like them. The only reason I am changing is a don't have dual-side entry. I test rode my bike with some store SPD's and nearly wrecked. I had to get the tension loosened to even get out cleanly.

We did 53.6 miles today. It was BEAUTIFUL!!! Sunny and 60's with practically no wind. The ride was a Beast, lots of climbing. I am sore but grateful to have logged 107 miles on a weekend the weather man thought would be ridiculously cold.
