Mike...what you're saying makes sense but it's easy to lose track of where you are depth wise if one has a senior moment, lol. Most times it doesn't matter as we're fishing relatively shallow water and send the jig to the bottom and back up again.
It depends on the jigging technique's you like to use as to what catches the most fish. I find that I catch a lot on the drop, also a lot on a fast retrieve up from the bottom also stopping at a certain depth and jigging as well as the twitch retrieve. A lot of times it's what you have the most faith in and therefore tend use most. I use the shimano butterfly jigs the most but also use the macdeep a lot as well.
If you ever want to try the Nanoose area look let me know and I'd take you out.
