As I understand it the new type wall support comes in two sizes, larger footprint for Planar 1,2,3 & 6, smaller footprint for 8 & 10 with the deck simply sitting on top using the pegs as a guide (RP 8 & 10 fits on the larger but needs the aluminium saucers). The lift in performance is a no brainer imo (I have a P9 sitting atop the original steel model). Rega say the new model is laser cut from 2mm aluminium and is lighter and stronger than the original, it has two fixing screws compared to three on the original. Looks fairly simple to fit if you're ok with a level, drill and tape measure. Perhaps Rega should put something on YouTube.
