Hmm, dont know what weight you are wanting to fish - I have been looking around as well....
will share what I have found - Some options mentioned already - T-Curve 10-15kg spin is grunty, but a bit heavy. Okuma 10-15kg 2 piece 8'6" looks ok on paper, have heard they are ok. Okuma 2 piece 7'6" braid concept - nice and light,I owned one but didnt push the 15kg end of the range, casts well, slim design. Xzoga takadum, 7'6" nice looking rod, rated up to 7kg of drag which isnt that high (for 24kg line etc)there may be other models. There are offshore models for 8-15kg/10-15kg, the ones I have seen have heavy duty fittings and they appear to be a bit heavy for fishing lures all day (but up to the job), the better popper rods are graphite slim line style i.e Daiwa Monster mesh- I managed to score one off TM, $199. rated 6-8PE but fishes 15kg (PE3)pretty good, nice tip for flicking 40gr lures, even though on paper its rated for 200gr lures. Have used teh 3 piece 12-24kg rod (was originally branded Youvella awesome I think) Nice rod, has teh grunt, I replaced teh guides with alconites, cast pretty good, a bit heavy to cast all day. If you want to go custom, CTS have some sea master popper blanks, 8' 30, 50, 80lb. The nice popper rods have a fair amount of graphite as they need to be strong and yet light to be cast all day. Ocean tackle International (US brand) have the Tuna Sniper rods, expensive, but by all accounts, they are good rods. I would say if you want a good value rod, check out the Pioneer Gt rods, very good value for money, less than $200, 2 piece, up to 8'3"
I am looking to get a 20-30lb 9' lightweight rod for casting poppers/lures but then for bait fishing etc. Been hard to find something suitable - has to be super light for casting all day, and grunty enough in the 30lb end. Shimano tiralejo 9' looks good, as does the Okuma Solaris 9' 20-40lb surf spinning rod, There is a Xzoga 9' 12-25lb that can handle the drag, not sure if I would like the parabolic action... havent quite decided yet, have been looking at getting maybe a CD graphcast blank or CTS blank and have a crack at making it myself. Will pair with a daiwa capricorn 4500j.
As has been said, the kilwell 15-24kg 1 piece spin rod is up to the task, offshore do a 15-24kg as well, grunty blank..... hope that helps... havent researched the Kilwell blanks yet, will drop them a line....
