For Diamonds that got the card, did you notice a big difference in upgrades clearing? As DM without the card, I am often 4-5 down the list and am batting about 50% on upgrades. If I got the Reserve (which I am considering because it comes with club access so I can use my third choice benefit for something), would it be a notable difference? Sure, specific routes have different variables, but generally speaking. Thoughts on when to apply for it to maximize the benefits?
