Yes, it's sort of a small 80 liter board. In that sort of language I would say it compares to a 74 FSW rather than an 80 FSW if you know what I mean.
But if you're skeptical I really think you should get you hands on one and demo (it could be any Acid 80 from 06 and forwards too...close enough to get a feel for it). It's just too much money to take this sort of leap of faith I reckon. Unless you buy used, then you will not loose much if you don't like it and decide to sell it.
