Another issue is that of line stretch. Mono stretches a lot more then Flouro. Personally, I use Silver Threat Excalibur, which is a copolymer for my baitcasters, and 20 lb Power Pro on my spinning reels. When I'm fishing really clear water, I change spools to to 10 lb Excalibur.

I went to the Bass Pro Shop in Myrtle Beach this week to buy a baitcast
reel. The reel I went to get was all sold out except the display one. I
hate to buy the display because they have been handled so much. The sales
person behind the counter showed me another reel that he claimed was the
same reel but it cost $30.00 less. I asked him if it was the same reel why
did it cost $30.00 less? He showed me a small oil port on the bottom of the
more expensive reel and he declared the only difference between the two
reels was the oil port. He said you are paying $30.00 extra for the
convenience of that oil fitting. They were the same brand and they did look
exactly alike. So I bought two of the cheaper reels with matching rods.

I then went over to the fishing line isle. Once again they were sold out of
what I wanted, 10 lb Fluorocarbon line. They had only one spool of the 10
lb and I needed two. So I bought one spool of 10 lb Fluorocarbon and one
spool 10 lb Monofilament. I have never fished with Fluorocarbon. I wanted
to try it because a friend of mind who knows far more about Bass fishing
than I do, thinks that Fluorocarbon is the greatest line ever.

When I got home I filled one reel with Fluorocarbon and the other reel with
Monofilament. I then attached a 3/8 oz practice plug to each rod and went
out into the yard to try out my new rods. I adjusted both reels as close as
I possibly could to be the same. I did not count how many cast I made but
it was a lot. Using identical brand new rods and reels I discovered that
the Fluorocarbon would cast from 15 to 20 yards further than the
Monofilament on every cast. Has anyone else experienced Fluorocarbon
casting better than Monofilament? James
