the seven wt. for me has been the stop-gap between the six and eight its easier to cast allday than the eight but has more back bone than the six,if your talking about nine foot rods.
i found a rod from cabelas that is the best of that whole spectrum its an eleven foot six weight the 1106-3FT.its a combo that comes with the anodised alum. big arbor sr2 reel and a legit wf.floating line . its a good bass rod with lots of backbone for the money (like 265.00).dont get it confused with the float tuber series. the F/T has a higher modulus than the float tuber therefor makiing it a faster action rod.
check it out and good luck.
