If you were running spoons, just keep going usually in the 2 to 2.5 mph range right now has been working for the guys running spoons. I have to admit I'm lazy and prefer running harnesses/spoon harnesses as I get better results with alot less line out. I'd rather run 15 to 45 back ( inlines/bouncers vs jets or mini disks) then 80 to 120 back. But if the bugs are bad, go with the spoons and keep a breeze on ya. Yes for me, when it lays down I will slow down using harnesses. Typically .8 to 1.2 max with 1mph average. I loose alot of fish that way when the mayfly hatch is going like it is now. As they don't bite real hard/solid but I tend to get alot more bites then if I was doing 1.4 up. Another trick is if your inlines are shallow enough to not snag bottom, do a semi hard turn to stall the boards on one side. We got a triple hook up yesterday and a double doing just that. Among those were short fish also but fun.
