Definitely. For the sake of 100 TPs, would you really want to drop to silver? It does depend on how much you make use of the benefits. But if you travel a fair amount, then you will miss out - especially if travelling through T5 a lot, where the F lounge will make a big difference. If you travel a lot stateside, then access to the AA Flagship lounges is the main benefit. And of course, your CIV score (c.v.) will mean less chance of an op-up when travelling BA metal.
