All imho, not sure though:
gen 1.1: no foam bulkheads;
gen 1.2: two foam bulkheads (see those greay foamy parts in hatch) = added weight;

gen 2.1: as 1.2 and the former orange in-mould decal at the nose replaced by epic logo;
additionall cover offered for soft hatch as retrofit
gen 2.2: dep. on dealer (?) > delivered with additional cover + screw attachments
In Europe, there are currently 2016s V7 (2.2 ?) and V5 selling at 995 Euros at some dealers (dropped from above 1300 Euros), wonder if there are such bargains now in the US, too?
I'd insist on the bulkheads (safety) and dep. on where you paddle also use the additional cover (not needed fot the flats, imo)
