It' s hard to ignore the hype of a new bow. It took me six years to finally part with enough money to buy a NEW primary bow. My Z-light still shoots good and I had a hard time justifying it. I finally got tired of wanting and did it. Now if it was a 2001 like yours, I' d wait and spend that money elsewhere.
$600.00+ could be a hunt of a lifetime on a manged ranch in your area.
Or new tires for the truck
.
Or invested until the bow you just have to have comes out, then withdrawl the $$ with interest or earnings.
Like straight arrow allready pointed out. The diffences are just not there to justify the spending on a new LX, that is unless you' ve got money to spare. Then by all means, spend away!!
