Firewire Mini Driver or CI Fred Rubble

Hi,
need some advice for my next surf board purschase.
I have been surfing now a js blackbox for the last 1.5 years. Really happy with the board. However, I miss sometimes performance in steeper/bigger waves (anyway I know that this board is not intended to perform in those kind waves)
6.0
20
2 1/2
31,4 LT
So I am looking for a "step up" board when the waves get bigger (for me around 6ft) or steeper. Very interested in quad fin option.
Thought about the Firewire Mini Driver 6.0 or the CI Fred Rubble 6.0
Any experience with those boards? At the moment I am more inclined towards the mini driver. Should I go with the firewire or with the lost original version?
Cheers
