Let's hope one of those 3 rails you're about to hit isn't slightly dead :frown:
There's two comfort zones here and i'm not in the same boat with you.
Maybe if this is something I did on a fairly routine basis I would go with that route. But, you're shooting from the far corner, to the other corner and coming back to that corner.. I just don't like the variables there. It's a lot of distance and unless I had been playing on that very table for the last few years and knew it like the back of my hand, I just couldn't feel comfortable doing that.
That said I think I would take my chances and run the 10 2 rails to the adjacent side almost parallel to the 15. If you can run the 15 all the way down ( assuming this is a 9 foot diamond? ) and get all the way to the other side, then run the 10 down.. I tip my hat.
However, i'll also take into account how my opponent has been shooting. If he hasn't really missed a ball and is making them with ease, i'd probably roll the 15 up against either of the solids as has been said.
But I just don't see two long straight shots going in and also getting behind the 8 ball ( assuming you're not banking it ) to run it also all the way down. Lots of CB movement on long rail shots.
