At the end of the day it’s another of those personal preference things. There’s no right or wrong here and I don’t think it matters if it’s an Enduro bike or not really.
It’s flats for me because they keep you honest. Instant feedback if you’ve done something wrong. You can also go and arse about on your bike for five minutes in your trainers and practice bunny hopping on the street. Yes, I’m a 30-something big kid really.
Seriously, it seems to me that SPDs are great for the Pro’s who already have perfect technique to begin with. They can tap into the final 5% of SPD performance.
Loved the part in the video after 5:25 results where he said he can’t bunny hop without SPDs.
If you’re riding (decent) flat pedals correctly your foot only comes off if you want it to and if you’re doing it right you can bunny hop until the cows come home on any bike.
When I do (very rarely) slip a pedal I know I made a mistake and need to think about better technique next time.
That’s my opinion and experience.
