It's a tough choice for something I may use very little at least for now.I have the Penn 109,which I haven't used,but not good for casting,but a tank of a reel for trolling.Some,or most say the c4 I will not be disappointed,others say,I will be disappointed.The 6600 is in a good price range,and available.Don't know?.Some say the 7000i is to big.The 4600 didn't see today,maybe a little early?.
