Updated my previous post: and here's a boot comparison.
2010 Burton Serows - 5.2 lb (size 9)
1998 Vans Shaun Palmers - 5.2 lb (size 10)
2011 Burton Sapphire - 4.2 lb (girlfriends size 8)
So the funny thing is that right down to the tenth of a pound, my old setup including boots weighed the same as my new setup. The new setup was 15 year newer top of the line shit. Big difference is the new board was 7.5 cm longer, 1 cm wider at the waist, 2 cm wider at the tip and tail, etc.
