Hey Donna, a great all-around 50lb blank for your application would be the United Composites US80 Tilefish, Fishy has a Stella on one, and it works great for 'hoo. That would probably work well for the 20, for the 30, I would go with the UC US80 Predator for a bit heavier work.
The rod of choice will depend on your applications. Popping rods are different from rods that you might use towards bombs. Bait rods, surface iron, mid water iron, etc... Though spinners are more forgiving for the angler who typically does not fully load a conventional rod on a cast the angler has more options and choices than one would normally think about on the West Coast. We carry them all at Bob Sands Tackle.. You are welcome to PM me if you have questions..
I have a Calstar gf700xh with a saltiga6500. For me the shorter rods balance better with the spinner, are much more comfortable to fish with and really give very little away in casting distance. I have fished poppers with it and see no need a buy a specialist rod instead of the versatile all-rounder.
That is exactly why it was more of a statement than a recommendation: "SEEMS to be good" along with the limitation "but I haven't caught anything on it that really tested it".
I'm careful with my recommendations to state what I know about a product, including the degree of personal experience. What I stated was at most a limited recommendation, fitting with my limited experience. A full recommendation would have been something like "I've been using this rod for 5 years and caught a lot of fish on its, its great for the job" or "I tried a Seeker Hercules 80xh and it bottomed out on 50# line; its better for 30# or 40# at the most" (something you witnessed first hand, ) .
Additionally, in a private message, I offered to loan the rod to Donna for her to test drive herself so that she could make her own judgement before buying it or anything else.
