I just returned from a very successful 6 day trip fishing for Great Lakes Salmon and while cleaning up and stowing my equipment I noticed this spot on the first ferrul up from the butt on my 9'-9" 8wt 3-piece St Croix LU (SCIV) that I built about 4 years ago. It appears that the rod flexure caused the wrap/epoxy to stretch and when returned to it's natural state creating a "bubble".

Is this something I need to be concerned about from the stand point of the structural integrity of the rod? Is this the point of impending rod faliure? Would you cut the wrap off and re-wrap and if so would you add an underwrap of white silk for greater strength?

Thanks for your comments!
