I have increased the adjustment radius to max also. It’s when you try to lower the line some after first raising it that you get a curve that has to be fixed. It’s not crucial. What I was studying was the difference in look when you adjust the coarse end versus the fine end. So, I was just goofing around with it and wondered is there a trick to getting a straight line that someone knew about, because it’s not in the manual. Apparently not, so I will make do with what works. Thanks for the replies.
