a 20/30 is a good all rounder that's why I got a 12/20 in braid and the boat as the boat is a stiffer action of the 2 and will handle a little more lead, but is still softer than a 20/30 blank the problem is all manufactures rods are a different action in the same class iv just got a century 20/40 braid and its more like a 15/30 to me but a light fast action rod will have more lifting power than a heavy though action as that will just fold up I think you need to have a look at the amount of lead you need then work from that as you can find a lighter class rod that you may over look due to its rating I find daiwa a soft rod for it's class but then the abu was a stiffer blank in its equivalent range
I know its different but go for what you like the look off and feels good in the hand then look at the action and see witch is best for you also why spend 100 an just 1 rod the shimano vengeance slim is a nice rod my friend got 2 a 12/20 & 20/30 for about 100 so have a shop around
Yes the Kenzaki 12/20 will be fine with those weights. I use heavier in the Solent on the spring tides. If its much above 1 lb leads I'd step up to 20/30 Kenzaki which feels like other 12/20 class rods. It is certainly much lighter than my Penn Waveblaster 20/30s.
I had a look at the new Suveran this week, it looks & feels like a trq or penn rampage and even resembles the shakespeare agility, NOT IMPRESSED!!! I think Purefishing have taken all the good brands & are badge engineering one blank and putting different fittings & badges on them. I won't be buying another rod from their stable,thats for sure. They have ruined Penn & Abu rods and they sure aren't going to maintain the 'cult' following for the Suverans with this rod. Just my opinion, but it looks & feels poor in comparison
