Hi - I've been surfing a performance noserider type longboard for a couple of years - 18 inch nose and 14 inch tail - wide point above centre. How does a log with a more pig shaped outline eg , smaller nose, wide point below the mid, and a wider tail, differ in terms of surfing? I can imagine they'll pick up waves easier with all that foam further back and maybe turn faster with the foot back on the fin, bog rails less??
