Michael Laverty turned the tables on his Suzuki counterpart Tommy Hill following the first day of British Superbike action at Mallory Park, the Ulsterman topping FP2.
FP1 pace setter Hill looked set to make it a clean sweep as he dominated for almost the entirety of the afternoon session, only for Laverty – who started on the front row last time he raced at Mallory Park in 2008 - to sneak ahead with a 56.115secs towards its conclusion.
Hill held onto second place to ensure the pair merely swapped positions, while Ryuichi Kiyonari gradually rose up the order to end the day in third position.
Michael's brother John maintained his strong form in fourth, the Buildbase Kawasaki rider well ahead of the number one MSS Colchester Kawasaki team.
Michael Rutter was another to carry his strong pace into FP2 with the fifth best lap, ahead of Honda trio Stuart Easton, Tommy Bridewell and Josh Brookes. Yukio Kagayama and Dan Linfoot ensured the top ten would have identical inductees to that of FP1.
Having been troubled by mechanical issues early on, Gary Mason was 11th best for MSS Colchester Kawasaki, ahead of returnee Karl Harris and debutant Andrew Pitt.
Coming back from injury this weekend, Simon Andrews and James Ellison, meanwhile, were 20th and 21st fastest respectively.
In the Evo class, Steve Brogan was the runaway leader on the Jentin BMW, the former Superstock winner up to 17th overall, well ahead of Chris Burns (23rd) and series leader Hudson Kennaugh (31st).
