Do I need a spare bow?

[NeilM]

This is about compound bows, but is not a specific compound discussion, so I hope this is the right place to post.

I have recently got right back into archery, although I have always been active. As a result I decided to invest in a new bow, a BowTech Constitution ( 05 model). I am VERY pleased with this bow and my shooting is much improved and so to my question.

As I shoot so well with this bow and as they are at bargain prices s/h in America, should I buy another, as a spare / backup ?

The alternative is of course to enjoy the bow I have until I feel the need for another update.

Note: I am a field archer, shoot fingers and am just about to start competing on a not too serious level.
