Dano Love the spinner tail on your Sutton 16.
Here is my Gomberg 60 with the Pennant tail. It has less drag than your full size tail for lighter winds. When the wind drops, I take the tail off and use a lighter line because the kite does not require a tail.
Like KaoS said. I have a rod in the leading edge. It also looks much better with the clean straight lines. My rod is in 3 pieces with a bungee cord inside so I can break it down and store in the kite bag and then easily reassemble.
