If you are going to "flip" I would use a heavy action rod at least 7ft 6inches in length. A longer rod would be even better for flipping to give you more distance with the "flip" and gives you more leverage. The reel to "flip" with doesn't matter much since you guide the line and bait out with your hand. The reel is used mostly to bring the bait back in.
Now if you are talking about "pitching" that is altogether a different technique. I would use a different rod and reel for "pitching" than I would for "flipping".
Right. He's gotta be Pitchin'. Ain't too many dedicated Flippers out there,anymore.
I Have disscuseded this on this board in the past, he may be confused with pitch'n ! I use a different rod and reel set-up for pitch'n depending on the conditions and lure weight.
