Thank for the info mate!
I am surprised on how much more cast weight that Demon Blood (90-230g) can handle compared to the similar sized Hyper (60-120g). Especially seeing as the PE8 rods of each have the same.
The Demon Blood is definitely a stiffer rod however don't let the quoted cast weights of the heavier Daiwa rods fool you. I won't throw anything more than 120g (including hooks) with the 762 and even then it's groaning under the weight.
As for the pe8 rods, that 150g-300g rating is pure fantasy. I had the Demon Blood 82xh as my intro heavy popping rod and it's definitely more of a pe6/130lb leader rod for throwing max 125g poppers and 150g sticks. over step these numbers and I found she'd groan hard on the cast and the small guides would cause some horrendous wind knots.
I must stress that these rods do just sit in my cupboard gathering dust as I have updated my rod arsenal to much better equipment but all in all, they'll do the job until you get hungry for more specialised rods or you want to target some bigger fish.
What species are you going to be targeting with this set-up? If you're hunting reef flats for coral trout etc, your other post regarding the Saragosa 8k or 10k becomes a little more clear cut. the 10k will be fine as, in my opinion, you don't want your lure travelling too fast in such shallow water making the 4.9 ratio of the 10k acceptable as it's kind of mid range between the usual low speed of 4.4 and the high speed of 5.6-6.2.
