Steeton find themselves leading Aire-Wharfe League Division One after the season opener, one of only two clubs to pick up the full 20 points available under the new scoring system.
The other was North Leeds, who trounced Knaresborough in Division Two.
John Akrigg (63), Neil Spragg (50) and Andrew Foulds (52) led the way as Steeton raced to 273-7 against last season's runners-up Bilton, to ensure the five batting bonus points.
Then Ross Suri picked up 4-40 as the visitors were bowled out for 210 to clinch maximum bowling points and victory.
Guiseley fell one wicket short of a maximum but had a very satisfying start with a win at Collingham.
Harrison Durkin (76) shared big stands with Peter Towner (54) and Brian Jackson (84) on the way to 284-8, and Nasir Jamal (4-47) and Chris Wain (3-72) restricted the home side to 207-9.
Jonathan Hughes marked Ilkley's return to the top flight after 20 years with 20 fours in his 110 and, with Nick Cockcroft (55) and new signing Dave Pennett (46) lending a hand, they reached 279-7.
Charlie Swallow and Bradley Ranford each hit half-centuries in the reply but Ben Rhydding were still 75 runs short of victory at the close.
Conor McInerney top-scored with 61 as Rawdon returned to the top flight with 227-8 but a towering six from James Wilcock gave Otley victory with three balls to spare.
Nick Brook hit an unbeaten 67 as Burley passed Pool's 163-7 with seven wickets in hand.
Skipton made a solid start to life after promotion to Division Two, Richard Nichols (79) and Steve Carling (68) seeing them to 251-7.
But a third-wicket century stand between Steve Shuttleworth (55) and Luke Stockhill (43) and a late flourish from Joe Lawrence (31no) saw Bolton Villas win by four wickets.
A five-wicket haul from Andrew Stothart restricted Follifoot to 209-8, and Thackley looked on the way to victory while Bradley Goodaire (56) and Luke Holroyd (35) were together but the tail collapsed from 121-4 to 163 all out.
Waleed Akhtar (54) top-scored in Green Lane's 184 but Upper Wharfedale eased home with seven wickets to spare.
Evergreen Mick Scott (3-25) and Nadeem Hanif (4-48) defended Tong Park Esholt's 195-8 and dismissed Colton for 172.
It looks like the two Horsforth sides could be mounting a strong challenge in Division Three this season after their new signings made an early mark.
South African Bev Williams hit a century on debut as Hall Park crushed newly-relegated Bardsey by 102 runs.
On the other side of town, Ryan Sharrocks made 84 on debut and, with Larry Edwards picking up 7-52, Horsforth beat Woodhouse.
Silsden finished rock bottom last season but started the new campaign with a win over Olicanian after Iqbal Khan (4-25) and Majid Inayat (3-41) bowled out the visitors for 184 in which Chris Wheeler made 89. Simon Cox (73) led the successful run chase.
Ben Brearley hit an unbeaten 75 in Addingham's 178-6 but Menston's Gareth Lee (65no) steered them to a two-wicket win.
Calverley's hopes to make an instant impact in their bid to bounce straight back from relegation took a knock when they went down by six wickets at New Rover, despite a half-century from Scott Driscoll.
