Hello,
Currently my two wrist spinning specific blogs are a bit of a mish-mash with the content all over the place, but still there and easily found if you spend a few seconds, just not in an order that I'd like to see it in. The re-organisation is happening and it's coming together slowly and here below is a link to the newest update with some really useful information that's seen elsewhere on the rare ocassion, but not spelt out as specifically as this I reckon. Interestingly, one of the commercial concerns on the internet http://www.pitchvision.com/academy are giving away some tips via emails and I've just received mine this morning and they're highlighting the same point as in my link below.
