From a Mfg's perspective I just want to say... the design is great but please
don't "pre stretch" your lines....
You can use your design to adjust your line lengths as they stretch out over time. On most brand's bars you can lengthen outside / shorten inside lines to accomodate for the front line stretch that happens with loops and general riding.
However, it is a nasty myth that it is somehow a good idea to torque on your lines to "pre-stretch" them. All you're likely to accomplish is unbalancing your line lengths and prematurely aging them. Your lines come tension loaded from the factory and brands like ours spend extra $$ on the better quality lines that are designed to stretch as little as possible!
Line stretch does happen though so you are always best to check your line lengths every 4-8 hours of riding and adjust as needed... but please - don't pre-stretch!
edit: that's a gorgeous back yard by the way!!
