I know it's hard not to worry, but, don't worry! Once in a while one of my RBTAs that normally opens to 8" will shrink up to the size of a golf ball. Now I can't say I don't get worried at all, but anywhere from an hour to 3 hours later it's back open and beautiful! Some of my new BTAs can take a month to really settle in and some look great from day one. BTAs are really a goofy nem without a lot of solid signs. Mags and Gigs can really show some 'for sure' signs, both good and bad - BTAs seem a little schizophrenic!! Lol
