Crotch………
I would say you should be more concerned about footwear/sole choice rather than pin length in my opinion. Had DMR V8 and V12 both had standard pins on current bike i have Nukeproof neutron also with standard pins. No problems with either of them the pins will bite into most soles , however i ride locally in some Salomon trail shoes which are fine mostly but if i wanted more “grip” at say a trail centre or mucky conditions then i would definitely be in my Five Ten shoes as the grip is superb in those i find. Or another “flat” riding shoe.
Just my opinion mind, based on only riding flats………as you know and mocked several times in the past 🙄
