Question for trainers

[Linny]

trainers and/or owners, a question?
If you have a horse which is eligible for (say) NW1x and enter in a nw1x/opt cl FOR the tag, what is the reasoning?
I know that in NY, the "tags" are often somewhat inflated, esp for 3yo's and if you can lure a buyer to spend the $$$, you'll take it. I've seen several such cases over the last few weeks in NY or FLA. As a handicapper I'm accustomed to seeing the horses in for the tag as the "better" stock in many cases. They are the ones who are beyond the conditition.
I'm finding these races challenging as I'm having a tough time classifying these horses.

I don't want anyone to divulge "trade secrets" or speak in specifics. I'd appreciate a general discussion.
