Futura 133 or 144?

[Revpod]

I'm a pretty standard intermediate sailor - 75 kg sail south coast UK, I'm looking to get a new Futura to partner with a 8.5 and 7.0 Tushingham Lightning - Would you go for the 133 or the 144? Will the 144 give earlier planing than the 133, because it is wider and has more volume - or will the 133 plane earlier because it is lighter ?!

Thanks in advance
