Always look at how far back you would have to cut to make the most efficient repair possible. There's times when we are being penny wise, but we frustrate ourselves due to not looking at the best way to get the job done. I charge extra for degree of difficulty, I don't want to add difficulty. It's really good to step back and look at the whole project. maybe you spend money on an extra coupling or two and save your sanity and time. Hope this helps. cvpools.com
