How odd. While I have my pads the same way as the wesspur site, I feed the straps through the other way...top strap out the back...
Not that it can really make much difference. I worked with a travelling Aussie vagabond climber who was seeing the world by stopping in and doing tree work a few months here and there at a time.
He wasn't very well equipped, so I had lent him my spurs from time to time. My old Buckinghams with the "aluminium" top caps. The foam backing was getting a bit dodgy, so he announces: " I believe I will wear them backwards today."
He put the left gaff on his right boot and the right on his left, with the pads supporting his calfs instead of against his shins. He got about eighty feet of a removal done before he switched off to me. I did the last fourty feet with them on "properly".
Just to be an arse, I blocked down to where he'd quit on the way up, roped out, and had him finish the spar. I noticed he put the spurs on the "right way" to finish it off.
But it was interesting to see that you don't have to be so anal about your spurs, how they go on, or which way the strap faces.
