They were big around Wakefield and West Yorkshire when I was much younger (like 20 odd yrs ago). I had one when in the juniors, as did team mates and they were ok but that's when Richard Wensley (ex Slazenger I think) was the maker. Think he sadly passed away a while ago though and is now the guy in the video. Never really see many now but two lads I know have them and one swears by em. I've tapped both up, ones very avg (but is old) the other is decent, but no better than that. I remember they used to have some funky shapes back in the day with bits cut out of the back etc.
