Old-timers are trying not to get too excited over the idea of 125-pound co-highweights in the $100,000 Valentine Dancer Handicap at Santa Anita Park on Saturday.

And with the scale of weights trending upward – maiden fillies carry 122 on the same card – the 125’s do not really threaten the memory of Forego and Discovery.
