Describes how responsive and immediate the power delivery is. SOFT = + Forgiving feel - Can lack responsiveness and feel SHARP = + Lots of feel and feedback - Less forgiving, particularly of riders with lower ability.

Describes whether the sail feels soft and flexible in your hands or firmer and more stiffly foiled. FLEXIBLE = + lots of feedback and feel - might not hold shape so well in gusts and stronger winds FIRM = + Good for stronger winds, power and control as the rig holds shape well - Can lack feel and sometimes more difficult to de- power.

Describes whether the sail feels light in the hands or grunty and 'powerful'. LIGHT = + Light manoeuvrable feeling sail - Requires sensitive technique in lighter winds GRUNTY = + Easy reassuring power - Can be harder work in stronger winds and wave riding.

Describes whether the sail feels more front hand or back hand pulling. BACK = + Usually preferred by heavier/stronger riders - Can be hard work in strong winds and down the line wave riding FRONT = + Great for high wind control and down the line wave riding - Can make the sail appear powerless in lighter winds.
