HI eveyone

I'm new to this forum. I'm having a couple of double bets on the weekend on the underwood/dubai. I'm from Perth so I'm biased towards Plastered. I was thinking

Plastered/Snitzel $70
Plastered/Regal Roller $56

I read someone mentioned Grey Song as it a wet track.. that sure throws in some value

Grey Song/Snitzel $260
Grey Song/Regal Roller $210
I'm probably way off the mark, I was wondering if anyone had some advice for this double bet?

Cheers

Russ
