I currently do 4K-6K spend every month on my Reserve. And pay it off monthly.
I see the Aspire is often recommended as the spend goes towards Hilton base points.

To get to Lifetime Diamond I need
2 million base points. I currently have 840,000 base points earned over 20 years.
I have more than 10 years Diamond.
I have 800, or so, paid and reward stays. It seems I need a 1000.

On reflection it looks like I should concentrate on getting the additional 200 and just stick with Reserve.

Opinions/advice welcomed.
