Routing Front Brake Flex Lines

I'm looking for some suggestions/pictures of how anyone has routed their front brake flex lines. I have a Heidts IFS with Wilwood brakes, and have been trying to come up with the best way to route the front flex lines. I plan on using thru-frame fittings to get to the outside of the frame rail, and I want to naturally keep the flex lines as short as possible without over-extending the lines at full wheel lock. So far I've come up with a 14" long flex line, with a 90 deg. fitting at the frame so that the flex faces forward, and also a 90 deg. fitting into the back of the caliper pointing vertical-up. I have the wheel turned to full lock and have tried this arrangement in both cases. It seems to work OK.
I have attached some photos showing both fully "compressed" and fully extended flex hose locations using a piece of vacuum tubing.
Another possibility, something that I saw in a book, was to run the flex line through the vertical axis of the ball joints (third photo), thereby creating the least amount of flex in the line as the wheel turns. This does however, put the flex out in front of the tire, unprotected.
I'd just like to hear from others to see how they have done theirs and get a few ideas, maybe something I haven't thought of.
