I just installed new shifter cables and I'm not sure if my RD housing should be shorter. I understand the principles of proper housing length (parallel exit and entry at the stop and the barrel adjuster), and I believe my housing meets these requirements, but my loop looks much larger than most examples I've seen on other people's bikes.
I based my setup on this image from Park Tool:

So what do you think? Too long? By the way, the bike does shift very nicely so far after a 30 min session on the rollers.
Thanks so much.
