Edinburgh pair Calum Atterbury and Glen Lewington claimed the boys' doubles.
The Capital duo knocked out top seeded Glasgow twins Matthew and Christopher Grimley 21-15 in the semi-finals and then went on to beat Stewart Dyce (Mauchline) and Ciar Pringle (Glasgow) 21-17 in the final. But Christopher ended Calum's hopes of a double with a marathon 25-23 win in the semi-finals of the boys' singles. In a family affair, Christopher then lost 13-21 to Matthew in the final. The twins were joint third seeds and they both caused shocks in the semi-finals as Matthew knocked out the top seed, Dyce 21-19.
