As far as KF Silver goes, you really have to see if you fly enough next year to justify $500 for 25% bonus!

Let's say you fly another 24K or so next year exclusively with SQ, MI or VS. That would yield 6K in bonus miles. At $500 spend to have to gain those miles you're basically spending $0.08 per mile! In contrast you can actually buy KF miles outright for $0.04!

Silver is not worth spending on.
