Curious,
with all the new designs out there and lightness of materials, what seems to be the boards size (NOT BRAND) of choice. Maybe if a few people could post their weight/height and board size for the general public it would be a good starting point to finding what works individually. As we all have different aspects that we look for.

I'll kick it off: 130cm - 75kg, 177cm - wood core for strength.

Just changed from a 122 to a 128, similar outline, but can't remember the widths. Im 70kgs and it hasnt made much difference to the low end but is oh so smooth on chop and has a nice wide stance.

Got a 143 x 40.
Works well in all winds. Even super strong winds when I tie my 5th line to the board for self landings.

A good formula is what fits under your arm is the right length twintip for all conditions (super strong/light breeze).
The width depends on your weight.
Im 90ish KG and can get good pop toeside from 40cm wide.
