i've been told my others inregards to gaffing out that it just doesn't happen on the geckos.
i tried them on and spiked up and down a 3ft section the other week, they didn't feel quite right to me, like the centre of gravity was wrong.
feel like the spike needs to point forward more.
i spoke to nod about this and he pointed out that the angle of the spike is the same as on the buckinghams etc....difference is the shank stays upright on your leg, whereas the buckinghams when you put your weight on the spike the shank skews off sideways making the spike point forward.
i wasn't really following him till i watched it happen while i was spiking.
still thinking about getting a pair of those carbon geckos though to match my sexy new black kong helmet when it arrives
