If you want a Pinstripe morph, which sex you buy depends on how much you like the morph, and what males you have. I like the Pinstripe, but not enough to want to make a ton of them, so I went with a female. Buying a male Pin lets you breed him to a few different females, but with no super, the male can never make you a super. By buying the female, and using a Pastel YB male or Sulfur mojave male, I can make my Pinstripes with my Pin female, and make awesome crosses with my double co dom males. I use the same logic for a Spider. I got a female Spider, bred her to my Sulfur Mojave male, made Sulfur Spiders, Mojave Spiders, and Spiders. I now have kept back the Sulfur Spider and Mojave Spider females, and have added a Cinnabee female by selling the Sulfur babies.
My opinion, buy males that can produce a Super. If you must have a Pin male, buy a LemonBlast or if you must have a Spider male, I say buy a Bee. Then you have your Super maker male, and your Pin or Spider making male.
