I actually like the blue oil idea to help people understand what's happening. It probably fools the pros sometimes as they read the breakdown more from the blue color than what's actually happened. Would be interesting to see it on your walled up THS, dark blue 10-10, nothing outside. Maybe then people can see how ridiculous those shots are... What's wrong with a nicely tapered shot 4:1 and just make people execute more without completely crushing their will...although most would probably stop bowling if they saw even 4:1 every night? OK, way off topic...
