are eggbeaters absolutely necessary (i know they are very popular, and i used to have a pair...)? right now i'm on a tight budget and all i have is cheap double sided mtb spd pedals, so i'm planning on using these. also, what kind of tension does everyone use, i just tightened mine up a lot and it seems like i stick getting out sometimes, so i'm guessing i need to loosen them a bit? and i'm planning on wearing my mtb shoes which have a lot of rubber on the bottom around the cleat to make them stable, but this slows down clipping in slightly i think, should i try to file them down a bit or something?
sorry for the long sentences, and thanks for any help.
