I've got a 703 and 743 DX, I'm starting to like the longer rods more, better casting distance, more leverage on hook sets. I'm using my 743 a lot more than my 703. 703 is a good rod, just too short IMO. But for you it may be a great rod.
On a side note, picked up a 784 a couple of months ago, really liking it for 1/2 oz t-rigs, jigs and Biffle head type jigs. It will work with 3/4 oz stuff also. Hook setting is really god with that long rod.
