Twice since 2009 I have more or less broke a reel. Once due to slides, once due to stupidly yanking a clearly stuck arrow. Could have kept fishing both times, but was pretty much beat each time and called it a day. I truly don't understand how some of you guys bust reels like you do. Remind me to never let any of you drive my boat or vehicle...I say one backup is enough.
On a related note, I broke an arrow off on the shot ttb for the first time ever a couple days back. I guess it is called the "mystery knot"? My 200ff wrapped around the string serving when the arrow let fly. I missed the fish thankfully and there was about 14" of 200ff left on the arrow when I pulled it out of the mud. I had not retied since probably last September, and I bowfished sporadically into December last season. Anyway, brady is right - it does break. I always expected that eventually that would happen when it was windy, but it wasn't really windy at the time. Just seemed like a regular shot with a "pluck". The 200ff dug into my serving a bit but the string looks intact.
