Need a bit of help I have a 5'10" SP which I find perfect, possibly could handle slightly less volume but like the volume in small waves to compete against crowds/longboards, do I go up to a 5'11" BP or go down to a 5'9" bearing in mind my weight is 103-105kgs with advanced capability. I am skeptical going smaller as I think I will miss the paddle ability of the SP and worried about going up in volume it might feel like too much volume.
