Ilkley, who are joint top of Division C with Harden, face their toughest test so far tomorrow when they take on third-placed Illingworth.
Nick Cockroft has marked his return from Burley with three vital spells of bowling that have netted him 15 victims.
Ilkley will need him to be in top form once again against an Illingworth side who are just a point behind them and last week smashed 286 off the Woodhouse attack.
Harden have a much easier- looking fixture at home to Alwoodley when skipper Anth-ony Bairstow will look to get among the runs again.
At the other end of the table, struggling Skipton can expect no mercy from a Colton side stung by defeat at New Rover last week while the two teams just above them, Addingham and Ben Rhydding, meet at Ilkley Road.
Menston can take heart from their batting display last week when only rain prevented them notching a first win and will feel confident going to Wood-house.
Jude Roberts' bowling and Barry Hawksworth's batting have lifted Bolton Villa's expectations, although they will be tested against New Rover. Steeton could find themselves alone at the top of the Division A tomorrow night.
They will be expected to overcome Green Lane while the two sides currently leading the table with them, Adel and Follifoot, face each other.
James Davies led the way for Otley as they got the better of North Leeds last week and a repeat of that batting performance would be invaluable against title hopefuls Kirkstall, who will look to bounce back from a dismal display.
Two of the struggling sides, Burley and Rawdon, meet while the other side with only a single point, Tong Park, are at home to North Leeds.
The match of the day in Division B is the clash between third-placed Silsden and Collingham, who share top spot with Beckwithshaw.
Calverley, who have overcome a first-week defeat with two victories, entertain Hall Park while Guiseley have the unenviable task of travelling to Beckwithshaw, who have bowled out each of their first three opponents.
Horsforth's first win will lift their spirits when they take on fellow strugglers Olicanian, while Thackley will be hopeful of a win at home to Upper Wharfedale.
