It'll work as long as the water temperatures are cooler. If you are trolling at 2.2 mph, you aren't going to get much depth with snap weights. I used to put some big drop weights on the line and I think the best it would get is 10' deep (my guess).
I basically attached a split ring to the end of my mono (or braid) line ... from here I clipped the drop weight (few ounces) and also attached a leader line about 6 to 8 ft long ... had to watch rookies didn't wind the line up to the split ring, and damage the first eye on the rod ...
