Spiders and Pinstripes are both gorgeous morphs. For me, its hard to pick between the two, but it all depends on what you want to make. If you are wanting a female, then you have your male pastel to breed with it, so if you get a female spider, you can make bumblebees. If you get a pinstripe, you can make pastel pins. Both are beautiful. It all depends on what you want to make though. If I were in your shoes though, I'd go for a pin girl.
Pins are gorgeous, but spiders always grabbed my attention also. Hmmm.. It's a hard choice
