i usually dont bait unless the pony is in horrible condition and even then, if i dont have it or i think someone else will want it i dont. I usually only bait G1 ponies who are unrecognizable... meaning they are common, so many in the same pose in the same color who have lost all their hair and most if not all their symbols and are stained. I usually try to save ponies, but that's just me. I bait if extremely mauled ie dog or knife or somewhat.. but i have done extreme restores, completely resculpting parts of the bods....seashell i wouldnt unless she was as previously stated. If not in that bad of condition you could restore her and maybe sell her for a little money if you decide not to keep her.
g3s are a little different. If it is an exclusive or holiday, no bait. If it is common and marked up and bad hair i say bait.
I usually end up getting ponies that are already prepped bait, and even then i end up restoring some because i know i dont have them yet. Like i bought a bait lot of baby sea ponies who had almost all their paint removed besides their eyes and were stained and missing all their hair and im ending up restoring them all! ha!
but it is your pony and your business. Thanks for asking though!!!
