The Badlands Hanover gelding is marching through the grades, winning two of his first four starts, and Armour quite likes the look of the 4yr-old.
But Armour is wary of some talented rivals for Jaccka Clubs in a 1-2 win mobile pace tomorrow, as Brindy, Maximan and Major Deed are all 3yr-olds with some upside to them.
''He's a nice horse going forward, but he meets a couple of nice ones at this stage of his career, but he is one to keep tabs on.''
Jaccka Clubs won at his second start in a 2.02.5 mile rate for the 2200m at Ascot Park on March 19, and comes into tomorrow's assignment on the back of a Winton victory on April 14.
Armour likes what he has seen of the gelding, and thinks he will be a nice horse in the making for owners and breeders Charlie and Ailsa Smaill.
''He's tough and he's started to develop a bit of speed, so he's becoming a bit of a versatile horse,'' he said.
Marshal Dale (race 3) gained a deserved win at Ascot Park on Sunday after finally getting a handy draw. The son of Knight Rainbow has another case of the barrier blues though, drawing the second line - although at least his major danger is right alongside him.
He's been going pretty honest,'' Armour said.
''The draw's not ideal, but the field's ideal - the hardest to beat will be El Diablo - but [Marshal Dale] should be a good each-way chance.''
''He should get a good run through from there and it should work out all right.''
Mullingar Mac was forced to do plenty of work in the claimers' pace at Forbury Park on Wednesday night and faded to ninth, but he will back up again tomorrow.
''It's a case of have horse, will race, with the claimers,'' Armour said.
Armour took his time getting the Road Machine gelding up to the gate on Wednesday night to ensure a clean start, and expect something similar tomorrow.
''Touch wood, at home he's a lovely horse, just obviously gets a bit wound up at times.''
Armour gave place chances to Taieri Wings (race 7) and John Henry Galleon (race 5) although he thinks a bit of Beaudiene Clemintyne (race 6), who comes into her non-winners pace on the back of two work-out wins.
''It's her first standing start at the races, but she's been going good,'' he said.
''If we can get a good run through and get handy, that will help. She just lacks a bit of speed.''
