I mostly go shore fishing3000 should be fine. Is it for pier fishing? The only reason you would want to go to the 4000 is if you like to use a heavier mono line. Im pretty sure the 3000 would have enough capacity for 12lb mono pier fishing.
I had the Stradic Ci4 3000 for about a month. Can't say I was overly impressed with it, at least not for the 200+ price tag.
I ended up returning it and trying the Quantum Smoke PTi. I've had the Smoke for about 2 months now. 50 bucks less, also extremely light, and over-all the action feels just as good if not better than the Stradic Ci4.
Food for thought.
Thanks guys, went to basspro today and decided to get the ci43000 and my wife got the fj. The fj feels more solid imo, So will try both of them.
