OK, just to piss on the parade a little, I used the #4 SLX on what was probably the HOTTEST day I have ever fished and strange things happened.
The Coastguard and I were up on a wee loch (don't ask where until he and I fish it properly
) in what was certainly 28C, possibly more. This loch is high in the hills and open to the beating sun all day. Factor 5000 was the order of the day!
The line went really odd - sticky, limp, wouldn't shoot or load the rod, gathered slack in the rear haul of a double haul and just refused to turn over, just crash.
Next day in better but still hot temps it was just fine. There was a breeze at Haddo for the anniversary bash so it was cooler, and that seemed to make a difference. It rolled, snaked, overhead and hauled just fine so if anything 26C is the cut off for this line.
This is not a complaint, just an observation. I LOVE this line! It makes me look good, and makes casting easy. It does what everyone else says of it. Fortunately those temperatures are rare in Scotland, thank god, and I'll probably never fish in those conditions again, but at least we now know what to expect if we do.
Great line Mike and it's about to get a whole lot of use! I like it with an Orvis 6' Superstrong 11.5lb tapered leader shoved up the core, popped out and nail knotted. Chop off a foot, add a loop to the end of the leader and loop to loop the three fly leader on to that and bingo presto hey - LOCHSTYLE!
Best line yet. Since we have an honest forum here, I thought I would share the experience.
