Ok, I finally took delivery of my 6'6" Q5. I'm a 90kg intermediate. I really like this board. I was looking for a 6'6" just like an Alternator but with a little more width. I thought "rather than ordering a CBD Alternator why not get a stock Q5 which has the width and volume I want, and I'll get that much quicker that a CBD Alt?" Great theory...12 weeks later I took delivery of the Q5. I'm sure a CBD Alt would have arrived in much the same timeframe.
So bearing in mind I was basically sfter a 6'6", 20" wide Alt, how does it go? It goes like I imagine a 6'6" swallow tail Alt with a 5 fin option would go; it rips. For me it felt really comfortable from the get go. I'm sure it will rip from waist to 2x overhead. At the lower end though it would need a pretty hollow wave - realistically its a board for chest high and up. It could easily be a good surfer's one board quiver, IMHO.
I also own a 6'4" Futura, which hasn't gelled with me after owning it for nearly a year. There's not an awful lot between the boards in some senses but the big differences are in the width, rocker and volume. The Futura carries 0.75" extra width, which is quite a lot. It has a flatter rocker but if anything it's nose and tail are more refined than the Q5. It has about 2 less litres of volume than my Q5. I find the Futura and Q5 paddle about the same across the flats. So far I am finding the Q5 is just a touch earlier into a wave because of, I imagine, it's extra volume. The Futura is unarguably faster across the wave on takeoff, which would be attributed to its width and relatively flatter rocker. Except that initial paddle in issue the Futura has a much lower end than the Q5. I reckon a good surfer could work this board in even knee high and up - certainly waist high and up. The boards probably have a similar top end but I do really "feel" the width of the Futura in more solid waves. The width doesn't seem to get in the way, but I feel its presence.
The Q5 is more a back foot board than the Futura, which surfers favouring a front foot style would love.
Both are excellent boards. The Q5 seems to suit my preferences better, but a more front footed surfer would probably favour the Futura. Having said that, the Futura would probably be a better all rounder. It could definitely be a one board quiver except big boppers over 95kg might need to look elsewhere.
