I don't know if it counts as "advice" coming from someone who hasn't done any breeding yet, but here are my thoughts...

I think Winston is pretty much out. I'm sure you have other girls who are a better pairing for him.

For a spider I'd want a reduced girl who also has a lot of gold coloration. I know you have no shortage of the first, and Pretzel doesn't look very golden, so I'd say that is out also.

Mojave would depend on if you like darker or lighter colored mojaves. Part of what I like in mojaves is the colors of their dorsal spots and the contrast it creates, and so I wouldn't be as interested in a black back mojave.

The tiger might result in the black back of the female canceling out the banded pattern, as Judy pointed out. Or it might have a really interesting effect, which I believe Albey mentioned. So even if you don't try it this year, you might want to try that cross at some point just to see what happens.

I'd go with the YB. One thing I haven't seen mentioned is that YBs tend to have their white borders turn yellow. Pretzel doesn't have particularly white borders to start out with, at least based on that picture, so it might compliment the YB look.

I definitely agree to go with the selective breeding idea of carefully picking which male to put with each female. However, I think the way I will approach it is to keep a second choice in mind just in case the first male doesn't seem to be getting the job done.
