Are you aware of the fact that the no-fee Hilton Visa is churnable (more than once per year)? Thus get it, use it for $1000 or $1500 in purchases (whatever the current offer at the time stipulates), gain 40k or 50k points, then repeat after a while. I don't see how you're ever going to come close to 40k or 50k HH points (or whatever the equivalent is) for every $1000 to $1500 in purchases.

You can't churn the SPG Amex, so all you can get there is less than 1500 SPG points for every $1500 in purhcases. I know SPG points are worth more cents per point than HHonors points, but not enough more to make up for the difference between 1500 and 50000 (or even 40000).

You can also get the Reserve card (but keep that one, for the ongoing Gold status). I'm not aware of the Reserve card being churnable (for more free weekend nights) the way the no-fee Visa is (for more bonus points).
