@gimruis, the 8 is where they matter most IMO. With a 9.5' I can make nice wide 8's while standing straight up, with the rod butt tucked under my arm. No contortions required, and I'm in a position where I have lots of leverage on the hookset.
As a side note: I'm very happy with my Daiwa Prorex rods. They're a lot of rod for the $$$. They're a bit overrated power wise though. I'd recommend buying one power up from what you think you need.
While I'm on the gear subject, the Piscifun Alijos 400 is an unbelievable reel for the $$$. Every bit as smooth as my Tranx and Lexa's for a LOT less money. Other than the graphite palming side plate, it's absolutely on par. I have the better part of the season on a couple now with zero issues. In fact the only thing I like about the Tranx better is it's size, and that's only when throwing smaller baits. Both my Tranx clutches like to engage occasionally when casting, and they have the worst line lay of the three reels. I don't see any more of them in my future. The Alijos is pretty much I identical in size to the Lexa.
