I googled spey rod and centrepin reels.. that actually sounds about right. Grandpa was an avid fly fisherman, and this was his heaviest rod (plus the hand written "steelhead"). i honestly have no idea though. I probably won't be visiting any pro shops soon though.
Chrom... Thanks for the invite for a PM. I prefer to stay public with my comments. I agree with you 100% re the professional world of rod building. I would not have it any other way! I was just saying that long rods can be used as center pin fishing set up depending on CONDITIONS! I have transitioned from skgit/spey to CP, covers more water (100yds or more) and more control for me on short runs all in one cast. Changing topic here, Why don't more peeps leave a bio about themselves? What are guys afraid of? Tony is 76 years old this month.
You can certainly use a 9-10' heavy salmon spinning rod for both salmon and surf perch to great good effect. Again, check the "lure weight" rating of the rod because that's the weight of the sinker's you'll be throwing.
Under 1-2 oz and you don't have enough weight to throw very far or keep the bait down in the surf. Over 3-4 oz is only needed in surf so rough you shouldn't be there anyway.
