I'm actually more worried about the seatpost slipping!
To help reduce likelihood of slipping, consider using some assembly paste (eg. Park SAC-1).. though if you're removing and substituting the post a lot, this is obviously a pain, and could lead to obvious scratching of the post if one's not careful (though hopefully below the visible area of the post).
