Looking at purchasing an Antares 1/30 Wave Secondary Mirror for my 10" f4.8 Newtonian in a Pimp your Scope Project. Orion Optics UK installed a 63mm Secondary in their VX Newtonians which equates to 2.48" imperial. Antares offers in their standard off the shelf sizes 2.14" or 2.6".

Question. Would it be best to go for the 2.14" or the 2.6"?
