I think you and I are in pretty different climates. We get lots of rain here during the summer (in a normal year), whereas Boise hardly gets any rain in the summer. (We average 4"-6" of rain during the summer months here, in a normal year). So many of those west coast varieties may work quite well for you.
I have less experience with the west coast varieties. I’ve tried a few, and most don’t work here, so I haven’t tried that many.
I suppose Baby Crawford is considered a west coast peach and it works well here. Another west coast peach I like is Spring Snow (Zaiger genetics). Beyond that most of the west coast peaches don’t work too well here (O’henry being one of the better ones, but still not good enough to keep for me.)
For the more wet tolerant peaches (which I’m more familiar with) probably Blazingstar is pretty top notch. I also really like Ernies Choice for flavor. Both aren’t what I would call consistent heavy producers, but both are very very good.
I would actually rate those two higher than Baby Crawford, even though Baby Crawford is an excellent peach. But of course tastes are very subjective.
Another peach which I don’t have a lot of experience with, but looks very very promising is Challenger. This is the second year I’ve harvested some. The peaches are a beautiful deep red and packed with flavor. Also seems to be a very productive peach, based upon the little experience I’ve had with it. It ripens with Blazingstar, and is every bit as good, but perhaps more productive.
I had very poor luck getting Coralstar to produce much at all for me. There are some east coast growers here on the forum for which Coralstar has done well, so it might do well for you.
Messina also sets very poorly for me and I will be removing that variety this year. There have been at least one report of it setting lightly on the east coast, so you may want to take another look at that one before planting it. I’ve fruited this variety for 4 years and every year it produces hardly anything (like a dozen peaches per full sized tree).
