I saw where Phil Marks used a prototype SK 10XD to help him win the FLW tournament at Sam Rayburn. I looked it up and that bait is huge. Looks to be almost 2x the size of the 5XD....(maybe that's why it is a 10XD) Supposedly it will dive approx. 25 ft on 15lb flourocarbon. Start working out guys, looks like this one will make you tired throwing it all day!
