The first leg is over 428m where the market principals are Black Sea and Idle Talker (19:45). Both have decent strike-rates, but in terms of Henlow form the black jacket has the edge with a better record here.
Carol Grasso's dog has recently been up at Sunderland in the classy Classic heats so that's the level he's raced at in recent years, and a 25.46sec run here in April still stands out. A fast start paves the way, although there is a danger to be found in a possible wide move from Sharpe early next door.
That would give well-drawn Black Sea a chance. He stepped up from two bends to four in good style last week and pounces if the local star is involved in any trouble.
The most competitive race of the night is over 460m at 20:15 where popular Henlow performer Westmead Rossi might be worth sticking with.
Nick Savva's dog has won two of his last three starts, so is really rolling again after a leanish spell. Remember, here's a dog with 26 wins from 74 races and as good a record at Henlow as any other in recent years, so when he's hot...
The danger would seem to be Swift Dartmoor. He has been showing good speed over 400m at Romford and does have winning form here to catch the eye from last November.
Still over the 460m trip, Minglers Toure (20:30) can land the third leg of the Flying Four.
From the same team which supplied Swift Dartmoor in the previous race, Mark Wallis' dog showed lots of pace in the Derby at Towcester and is ready to pile on the pressure from traps here.
He has been running as a railer but this switch to middle seeing - and a trap five draw - can help his trapping and a smash break sets things up into the turn and onwards?
The last leg of the Flying Four is a 550m Midi where there is a red-hot favourite in the Wallis-trained Garryglass Teddy.
However, at the odds, there could be mileage is siding with Buckos Lass (21:15). Corren Price's dog trialled well here and is capable of smash-breaking which could put pressure on the hotpot inside, especially with Teddy likely to rail early.
Thereafter, Monmore raider Buckos Lass might take some holding given 590m wins at Belle Vue.
