Hi Acuatico,
I'm not a big expert but I think both boards are almost the same.
(experts, please correct me if I'm wrong)
I also weigh 75kg and I'm also looking for a board like this but with a bit more stabilty.
I have a SB Converse (9'0" 137L) now.
I think the stabilty is the same looking at the width and volume.
For me last years 8'5" pro would be good (123L)...
I have to say I'm a SB guy so I would pick the Pro
it's like having to choose between a BMW and a Merc

I'm waiting to read more about the new boards on forums once they arrive in the shops and people bought or tested them. the 120L 7'8" x 32" wide point is also a board I want to read reviews about.
I live in Belgium en winter is on its way so no chance for a testday over here...
