Nitro Mystique 149/152 - fun, forgiving, stable and gullwing chamber to grip on ice.
K2 Eco Pop 148/152 - Nice Pop, Stable and fast.
Gnu B-nice 148/151 - Do it all board. Magne traction for ice, Banana for catch free ride.
Roxy Ollie Pop 148/151 - Soft and forgiving, magne traction and C2 banana for added control.
Gnu B-pro 149 - Similar to Roxy Ollie pop, wider waist and faster base.
I think you should go for a little bit longer board around 150 because of your ridingstyle. Your bootsize fits a bit wider boards to. Go for a soft board because of your weight!
