First YB looks good with anything it really is a bonus when you get in to multi gene morphs. With the price range you are working with you have endless possibilities! Is this quick decision for this season or are you planning for future breeding projects? If you want my personal opinion I’m really into Sugars, and leopards and clowns right now. Always remember you could never go wrong with an enchi, or fire. I advise you base your decision on what snake you really wanted to work with next or like the most and aim to pick up a double gene specimen oppose to a single gene.
