Howdy,
RT on your float/jig question my advice would be to use a simple clinch knot to attatch the jig. For two reasons, first that knot grabs the eyelet tighter than most, and to ease the task of changing colors it can be undone with your thumb/finger nails. Also the clinch has like 80-85% breaking strength which I like, so as to avoid the line snapping off near your hand snarling a run with all that mono.
My tip is on spoon fishing for river Humpys.(can ya feel em coming) While pink spoons are tried and true producers, plain metallic finishes (chrome, brass) can be just as effective many times(red too) My real gem is a technique known as the Meisner twitch (named after its inventer) Cast out and slightly upcurrent of a horde of Pinks, and count down your spoon to what you suspect would be a foot or two off the bottom( as a rule of thumb I count a foot a second) counting will allow you to get a good feel of what is the danger zone saving you from snagging bottom or that log the fish love hiding around. The twitch is accomplished by dead drifting until the spoon swings nearly in front of your position and its weight is signaling a no slack situation between rod tip and lure. Now just wiggle that rod tip much like a timid K-mart shopper would while testing new rods in the sporting goods asile. No jerking, just that tip rapidly going past center a couple inches each way as fast and spastic as you can. Try doing this acouple feet under water in front of you to see the desired flutter/twinkle action this will impart on the spoon. Just don't be suprised if a gang of Humps appears right there in front of you all doing the death dance trying to grab what I think they take for a small batch of krill. Have some fun.
