Yes, I certainly wouldn't be relying on the late mail either. I looked back at how they went on Saturday and it wasn't good. One thing I've noticed though. When the late mail horse is at $10 or longer in the betting, it can sometimes make a nice each way or place bet. It doesn't happen often though, so you'd have to be patient. Just two on Saturday:
MR5-6 Songs Of Vienna PLA $3.00
MR8-2 Econsul PLA $2.90
