Hey folks, new to this bocking lark (ie haven't strapped them on yet until I get some proper protective gear, I'm pushing 40, a martial artist and I like my body unbroken!) so this info is really helpful, thanks.
Just to let you know, I tried that discount code at Alps Gear and it doesn't work any more. But on a hunch I put Flexmeter into Amazon, and there they were, being sold by Alps Gear, but (and this is the important bit) with FREE delivery! So that's like £4 off anyway.
So if you want to buy them, get them off Amazon.
Really looking forward to this, can't wait to get started!
