If it is my hand ties I carry six. If I start catching more fish than my fishing partner he will want one. Then we will loose one or two to a toothy northern or large bass. Lastly one lost to a break off in heavy weeds.
Of course there is no way my partners are going to return a hot lure,any way I don't like to see a grown man cry. :-)
Starting out with six at best I come home with three left. Time to tie up a few more.
