It's not a bad dilemma to have. Apart from the weight and extended set up time there are much fewer compromises with solid floor SIBs.
If I was going solid floor then I'd go for a nice classic Avon or Zodiac in Hypalon. So many Avons' around and considering the remarkable quality you can't go wrong.
Said the man who just bought a Y Class.
If new then the Classic is a great choice or as JK says stick with Bombard.
I won't argue that (given all general SIB-important factors) the Aerotec is the 'ultimate' all-round SIB and I would not sell the Aerotec just in case...
