I've got two bows I bought, tuned, shot a bit, then retired them. Both Blackwidow PLX take-downs, one 65lb and the other 55lb.
Bought them when I had the money, because I know I'll not be able to shoot my 75lb PLX take-down forever.
So, those two will stay in "retirement" till I need them. Although I do very occasionally take them out and shoot a few arrows.
Just love my 75lb'er, I shoot it a lot, and I usually shoot it pretty well too.
That's my take on bow "retirement"
