Yes I was on the lower provo, where the browns get really spooky from pressure.
Of course, the best plan is technique, to spot the fish and not cast over them. But sometimes it happens.
Most of the time it probably doesn't make a difference. but if i were to buy a new flyline, why wouldn't I buy clear?
I am not sure if they are as strong, or cast as well, as other fly lines. Then there is the issue of whether they work too well, and you can lose sight of your own fly line. Like when times I am spotting a fish while stripping in, I take my eye off the line to find the fish, then look back. So those three questions are unknown to me.
