If I were you, you could do one of three.
1. You could go to the store, and just test out all the ones there and focus on FEEL. But as you said, it looks like you are looking for better demo.
2. You live in Cali, I'm pretty sure there are store that let you demo( I think so, but in Canada I have yet found a dealer that will lend it out to me).
3. If the clubs aren't urgent for you, wait until manufacturers have a demo event at a certain golfing range or golf course.
Maybe one more, go with the reviews.
Good luck with your choice.
