5 10s maybe a little more expensive but they are significantly better than the competition. For the price difference its easily justifiable. Most flat pedal riders will use 5 10s, the stealth rubber grips like a limpet and you actually need to lift your foot off the pedal to move it.
Once you’ve got 5 10s, your pedal choice is pretty much down to quality, price and how replaceable the pins are.
You’ll see three types of pins – ones that screw in from the back using an allen key (Burgtec, Atom Lab, NC17 etc), ones that screw in from the top also using an allen key into the top of the pin (Shimano DX, Easton Flat Boy & Cully, DMR etc) and ones that screw in from the top using a hexagonol nut at the base of the pin (Straightline).
The problem with pins that have the allen key in their top, is that as soon as you smash your pedal on a rock, you ruin the hex and getting the pins out is a pain or in some cases impossible. If you get ones that screw in from the back, you can always hacksaw off the bent bit before removing them.
IMO the best pins are the ones that screw in from the top using a hexagonal wrench as these present the least amount of fuss. Having said that, the pins in my Burgtecs are still in perfect order 2 years down the line even though they’ve been smashed to ****. The Burgtecs are seriously expensive though.
