Not quite so heavy - about 1.6kg vs 2.3kg - but I have had no problem usign a 165mm Super Angulon onthe Phillips 8x10 - felt as solid as anythign else - I never felt the standard locks were close to not beign able to hold it.
In fact I used to have a huge 12" 4.5 lens in a massive Betax shutter that I'm sure probably weighed more and again, it never seemed a problem
