I have a Torr Goldfinger with a convex base, think it is 54.50mm. I want to move over to a flat base so that the sides of the puck ‘seal’ better. I am using whatever that IMS basket is us Evo Leva owners use. Can anyone suggest either a new base that would fit the Torr or a new tamper please. I will contact Jens at Torr and see my options as well. Many ta’s
