Paul,
This is the Jigging Master 2007 jigging bag, I designed it to be better than everything else! It takes jigs to 40cm and has a removable middle section for shorter jigs. Additional mid sections for more long jigs are also available. This bag holds a huge quantity of jigs, I think I have 70 in mine with both mid sections inserted (and yes I have to work out to carry it!) It has a very large external pocket for terminals and as with all JM accessories, construction is very very solid.
You can order it through Tackleworld stores.
