Wow, standalone, you are a dink! Part of any forum website is asking questions and helping others. I've been fishing for a while and know a thing or two, but I still use FWR quite often to bounce ideas off other users, get some opinions, or whatever. Just when I think I "know everything" I find someone who knows more and can teach me something. Anyway, you must be a hit at parties buddy. Moving on...
I clicked on the link and can not see where some spinning rods are labeled spinning and some are west coast spinning. Sorry.
What I will say is yes sometimes smaller lures are the key around here, especially when the water is low and clear in the late summer and early fall. The reason is a bigger lure (spoon or spinner), say 1/4 oz or whatever, is just way too big and flashy in the water. The fish, esp coho, will avoid it. However let's say you downsize to a pretty small lure, 3/16 or whatever. Often this smaller "presentation" is enough to grab the fish's attention, but not so much that it spooks/scares it. It's a balance between not going so small that the fish do not notice it, and not so big that it spooks them. Depending on the day, water clarity, how many anglers are casting in the water (more ppl casting = fish are more spooked), what species of fish are in the water (some more easily spooked than others) and perhaps some other variables will determine what lure size and color is the most effective. It's all about trial and error! Some days your choices suck and you catch nothing. Other days your choices are bang on, you're catching all the fish and everyone thinks you're "the man" (or "the woman.")
Lure choice and best rod choice are correlated. If you have too heavy/beefy of a rod, it is really hard to cast light lures any distance or feel their action in the water. But if you go too light yeah you can cast far, but the rod has no backbone and you will struggle to land your targeted species.
Any of the shakespear rods that are medium-light or medium and over 8 feet would be fine IMO.
I will add that, while it is tempting to get a super cheap rod online, after shipping you are probably not going to save a lot compared to going to your local tackle shop. Im not sure where you live but all the LM tackle shops will have budget friendly rods, reels, and so on. A Shimano Convergence or similar entry level spinning rod is only 70-90 bucks. And if you get the staff to help you, you KNOW that this rod is going to work well for what you're using it for. If you buy online it might work out or the rod might suck, then you are stuck with it and have to buy a new rod. Best to "buy once, cry once."
