If you're going for the alcans, share with them how much weight you carry normally and then how much you might add for trips (like luggage, stuff, etc) so that they can plan for it.
I'd suggest getting something that is just a bit more height than what you have now so that you can deal with some settling. Then, when they eventually need refurbishing, it'll be something that you can do at a local spring shop.
