Yeah, for me it's colors. The reason I keep collecting X's is because I don't feel like changing lenses and rubbers all the time.I always swear "this is the last one I swear" and she knows me well enough to call bs on me, and then I'm like "well, if you say so, I guess it won't be the last pair!" and then I go hunting again, and blame it on her! It's all her fault really
