Hi all!

First off, I'd like to thank everybody for sharing their knowledge in these forums for newbie fixed gear riders like me. I have learned a lot since the first time I logged in, so thanks!

To get this out of the way, I have been searching both in and out the forums about clipless pedals on fixed gear bicycles. The general consensus is that MTB clipless systems are great coz they're pretty secure as well as the shoes being walkable. I was looking at Time ATACs and Eggbeaters, and they both seem to be very popular for fixie riders. However, I also read Carleton's post about using Road Pedals and Shoe combo. I think thats also a great suggestion as these shoes were made for pavement riding and longer rides (which I currently do with my fixie).

I know this has been a topic that has been discussed over and over again. But I couldn't seem to decide on a setup that fits my needs. I do ride everyday mostly for training and fitness, and go on longer rides and club rides on the weekends. I do also go out on more relaxed rides with my friends. Also, I have never ever used any type of clipless pedals in my life (I am currently using clips and straps). I'd want something that would be easy to learn, as well as versatile enough that my options for shoes are not limited.

So I need your expert advice, I'm looking at these:
1) Shimano SPD - I am not really knowledgeable with different types, I believe there's more than one. But it looks like its the "standard" for roadbiking as well as MTB. It's also nice that Chrome makes sneakers that are SPD compatible, definitely a plus.

2) Time ATAC - just by eyeballing the pedal, it looks like its chunky but very sturdy. I am concerned that the pedal with the shoe would be quite heavy?

3) Crank Brother's Eggbeater - Minimalist design and with multiple entry points. I 've heard that theyre really easy to get in and out of. I'm quite concerned how it can hold up to abuse. I don't skid, but I ride pretty hard. Also, since the pedals itself are small, I've heard people say that they develop "hotspots" on longer rides.

4) Look - They seem to be similar to Shimano's. I haven't really looked at them that much but they seem to be very popular with the roadie crowd.

Last question, except for the Eggbeaters, do all clipless pedals clip out via a twisting motion?

Your thoughts, comments and inputs are greatly appreciated. If you think there's a thread that I missed out or a webpage that could guide me in my decision please feel free to post it.

Thanks everybody!
