FMIL sent us champagne glasses as an engagement gift. They are waterford crystal and very heavy (and expensive!)- I think her intention was that we use them for the wedding...but I would just prefer to use what the venue provides.. (less chance of breaking the nice ones, one less thing to lug back and forth) etc etc... is it common to bring your own fancy champagne glasses to your wedding or do most people just use what the venue provides?
