This is the point where someone repeats that Dean and Tony have both said that there was an intentional decision to try and make all of the lasts fit the same so that, if the 11 works well for you in MH71, an 11 should also work well for you in the TG73.
This was my experience with the Deco last and TG73.
They don´t fit the same for me. I wear:
GG06 and MH71 = UK7.5E
DG70 and MH73 = UK8E
In this sizes the shoes fit the same, nice and snug.
