You’ve got loads of options at £30. For similar money to that I’ve got Wellgo mg1’s on my hardtail play bike which are very light and quite grippy. On my FS I’ve got exotic alloy flats – they’re a little heavier than the mg1’s (that’ll be the aluminium alloy vs magnesium), but a lot tougher / a little wider and grippier.
Out the two I’d go for the exotic’s again I think. With 5-10’s they’re amazing. They’ve had some hefty rock strikes and just keep coming back for more.
Equally I’ve had a go on some of the plastic pedals that are around these days and they’re pretty good and very light. Electrons / Horizons / Chesters etc. I prefer alloy for no real reason.

The Wellgo’s looked so nice out of the box – they’re a white with a pearlescent flip / sparkle to them – but loads of the paint has rubbed off and they look much less nice now. The exotics are holding up much better.
