I've never been in a boat with somebody that can throw a 5XD to an 8XD farther than I can with my Abu Garcia Veracity 7'11 paired with a Revo Winch. Will chunk those baits a mile. Never thrown a 10XD, but it handles an 8XD with no problem.
Well who have you been up against and what equipment were they using? That makes a huge difference. I can get some pretty good distance out of my Daiwa Tatula CT and my 7-11 Duckett Micro Magic as well. I would be up for a fun casting contest...
I have thrown the 10 on the Duckett but only for a couple of casts because it really isn't designed for a bait that heavy.
The Dobyns 806 is better for the 10 XD.
