So my dad and I both made the switch to clipless pedals... sort of. Step 1 was his bike (brand new) and he was the one who actually took the old pedals off with the bike wrench. Then I put on his new pedals and voila - clipless! Then, I went back to my place to do the same to my bike (bought summer '08). Failure. Can't seem to loosen the pedals no matter how hard I try. The truth is, I'm not even sure how I could grease it up so it could come out. I'm thinking of calling a guy friend over to see if someone else has better luck and then taking it to the LBS with my tail between my legs.

Any advice?
