Lesser spider or lesser pin would open you up to more variety when breeding. Some people tend to stay away from spider morphs because theyre pattern is linked to their nervous system and it tends to make them "wobble" shake and corkscrew when excited and in some cases complicates feedings as a result. Personally I find the morphs containing spider genetics stunning and choose to collect and plan to breed them regardless. But thats the only thing I would say MAY put lesser pin in first here.
Edit: That was in terms of breeding though. Im afraid I dont know the market value of retics, or lessers off the top of my head, so I cant comment there.
