Hey there. Not sure if this helps but... I have a 2014 Mondo with 650lbs in the rear lockers and a 750lb IBS and manual flow. This is our first year surfing and i have a 5'4" Ronix Cortez and pretty much anybody that has tried the board can surf without the rope after an hour of time behind the boat. I have been cranking turns and think the board surfs fine (no other experience so far). crazy loose with the center fin off. Ok that was background.....

Last weekend, a neighbor at the lake borrowed his brother-in-law's LF Fish 5'6". I found it REALLY slow. it seemed to want to fall back out of the pocked all of the time. I found it hard to drive and get speed. My neighbor commented that he also found the Cortez easier to stay in the pocket. Take from that what you will.
