I agree. I've done Harewood House and GTi International and really enjoyed both of them but I was pretty disappointed with Ultimate Dubs. There were some nice examples of various things, particularly ones from Europe which haven't popped up at the other two shows before but there was a major lack of stalls in my opinion. I only found two tuners cos I'm looking into remapping the Mk6 and didn't find any jumble stalls where I might pick up stuff for the Mk2. And, obviously, with the other two being outdoor you can have a picnic and chill in the sun etc. as opposed to wondering round a large shed. And, as stated, the traffic was horrendous, particularly as you get bundled in with all the local traffic going to ASDA and the shopping centre next door.
I'm glad I've been to say I've been but don't think I'd go again.
