Opinion on Rolling Doubles?

[Scav]

Seems like this is the new hot thing for tracks to do. Wondering what people think about it. Arlington's early/late DD get about 20k, where the others throughout the card get about 5k. I think that 5k throughout the card, is getting pulled away from the P3.....

I think I would rather see them have an early/midday/late DD then rolling DD's, to keep some of the money within the P3 pools instead
