Would you be comfortable upsizing to the 159? We have the same riding style and pretty much the same stats (~160 lbs, 5'7, boot 9). I've been riding on a 156 and love the size, but my local store only has a 159 left. I can buy the 156 online, but would love to support my store if I can. I know its only 3 cm, but wanted your input.
Definitely someone our size and skill level could ride a 159... BUTTT the 156 for me is nearly PERFECT... soooo quick with turn initiation and yet super stable charging through chunder. I do have a pure pow board for snorkel days so if you're going for a single board 'quiver' you could be fine on the 159.
