I am looking to get my new Triban 3 new single-sided SPD pedals (so I can use them easily without specialized shoes too) (also, yes, I prefer to get SPDs rather than SPD-SLs), initially was looking at Shimano A530 and A520, but then decided it would be nice to have a little bit more under the foot even in normal shoes, so then T780 and PDM324 came into picture, with the latter being on top of the list now. Any opinions on them? Or other recommendations?
