Otter,
Looks like you have been having some fun!! Nice girth on that Musky!! It's funny, I have used that exact lure many times targeting walleye with little luck. Just goes to show you how important presentation is. Keep hauling them in and keep up the pics!!
Also, how long of a leader are you using on the fireline and how are you attaching it? I usually use a barrel swivel but end up reeling it into my guides more often than not
