Monahan Tweed - Each Way, can't go wrong.

16th Oct. 1400m Caulfield
1st - Amtrak, barrier 7, 53.5kg = lead all way.
2nd - Pink Fit, barrier 8, 52kg = box seat
3rd - Monahan Tweed, barrier 13, 53.5kg = 3 wide no cover

Tomorrow - Sandown (no leaders track)
Amtrak - barrier 13, 56.5kg
Pink Fit - barrier 11, 53kg
Monahan Tweed - barrier 4, 54kg.

admittedly Amtrak did beat Monahan Tweed last start but goes up in weight again, and I can just see Monahan Tweed box seating behind Amtrak with the run of the race, so $7.50 looks a good bet.
