Otherwise, any recommendation for "cheapo/reasonnable" quality MTB cranks would be appreciated.
Sugino/Stronglight XD-2 would be perfect for this bike, and only £35. Spa sell it without rings too for £20. Great quality for the money and certainly not heavy.
I suspect that the square taper was damaged from being slightly loose while you performed all these bunny hops. Unlikely to be a problem if properly tightened and regularly checked.
I would keep the road crankset for a modern road bike - it would look incongruous on this bike.
