I just switched to my first set of clipless pedals last week after 2 mos of cage riding on my very first road bike and I LOVE them! However, this really seems to come down to each individual person. I know that when I bought my bike a couple of months ago, I didn't even consider taking off the cages for clipless pedals because I was inexperienced and under the impression that an amateur like me didn't really need them. Let me just say though, that after the first week of riding, I HATED the cages with a passion.

I hated the constant reaching down to tighten and loosen, and never felt that I was being especially efficient on my rides. I haven't found it so far to be difficult at all to adjust to the pedals and remember to unclip before coming to a stop. For some reason, my brain is hyper sensative to the pedals and so far I have remembered to unclip everytime. Perhaps it's all of the painful cautionary tales that I have read here that help me remember!

Anyway, just go with your gut. I don't think I have been affected by not starting with clipless right away, so if you give the cages a shot and then move on, you really haven't lost anything in my opinion. At least then you will be sure about the move from the cages to clipless. Good luck!
