YMFB, I thought they stopped doing the two sizes of top boxes a couple of years ago? When I got mine they only had a mid-range one. (42ishL still takes two helmets). There should be some posts in the history about that.
Diveguide, YD is yorkshire Divers (
www.yorkshire-divers.co.uk) a very good UK online dive club (think DSC for divers). There is a poster on there called yellowduke so I thought you may be one and the same.
Anyway, check it out, there are quite a lot of active divers on there.
