I just switched from SPD to Look style and the latter are much easier to get in and out of IMO...the SPD were smaller and took more effort to clip in....once in though they are pretty much the same...no you don't need to learn any new secrets!!...you will pedal more efficiently though....they aren't made for walking so I just put them on nest to the car and get on the bike, and reverse when I get back...most shoes will accomodate both SPD or Look cleats....SPD take 2 bolts and Look style take 3....hope this helps!
