We are not sure reducing CL length and save 2-3cm it's worth, by using a different QR attachment saves more centimeters and is more simple.
About rings, we decided to respond to demand of "low friction sliding ring" and we are testing a new product like the ANTAL ring but in plastic.
It is designed to fit the CL tube and retain it to avoid unwanted exit from the ring and let the tube slip off when the QR is activated. This is the shape without retain system and as soon as we test it we will let you know. About having the bar as close as possible to the body I remind wavers that the right style and position is this, the hand is far from the body almost all the time when surfing the wave.
A good trim of the bar can solve the depower issue.
