Bike #1 is set up for shimano spd and mtb. shoes. When I purchased bike #2, I wasn't sure exactly how I wanted to go, remain with spd's or go with road pedals and shoes. I purchased nashbars version of spd's and rode almost 1000 miles, getting used to my bike, then I made the decision to change over to road shoes and pedals. I like the ease of walking (up hills) in my mtb. shoes, but I put the cleat covers on the shoes and walk, just a little more awkward. I like the accesibility of my spds, meaning both sides I can clip into. My Look pedals are weighted, and usually end up side down and takes me a little to get my other foot clipped in once I"m starting out. I do feel the performance is better with the road shoe, my opinion or imagination?!? Just some ideas to ponder, but you should do whatever makes you feel comfortable and is best for you. I have no intention of changing over bike #1 to road attire..and both my bikes are road bikes BTW.
