Which of my 30 some odd rod/reel outfits do you want me to expound on
But, seriously ... the heaviest action rod I use is a 7' med action IM7 Bionic Blade, which has a Shimano Spirex 2000 reel spooled with 10/2 PowerPro braid, which I use to cast baits heavier than a 1/16oz jig.
For most all other casting or dock shooting use ... I use a 6'6" IM6 ESP PowerLite (fast action tip) with a Okuma Stratus STX20 reel spooled with 6# test Vicious Panfish hi-vis copoly line.
My secondary/backup rod is a 6' Ardent IM7 rod, with a Shimano Spirex 1000RE reel spooled with the same Vicious copoly line.
Of course, if you ask a hundred people what rods/reels to use, you're likely to get almost as many different answers. Some will say go high end and never look back, while others will say go cheap and replace as needed, and even others that say look for something in between. My suggestion is ... regardless of what brand/style/length you decide on, make sure the reel balances well with the rod. A rod/reel that's a little handle end heavy is MUCH better than one that's tip end heavy, because a tip end heavy outfit will wear you out within a short time of use ... especially if you're casting with it.
The techniques you intend to use will dictate what outfits you will need. Some will allow you to use them for more than one technique, while others are obviously technique specific.
