Anyone got an actual real life weight on a Super Record Ti crankset (53/39 175mm) ?

When I look at shops there are almost as many different weights claimed as there are shops.
Even camp's own site has same weight on all cranks, no matter if its 170mm or 175mm, compact or not - which hardly seems correct either.

Here you go, a comparison of the 2009/2010 Super Record Crank, the 2011 Ti Super Record Crank, and the Campy/SRM Crank

Weights (all cranks are 175mm with 53/39 chainrings):
Lightest to Heaviest:
2011 Super Record Ti: 596 grams
2009/2010 Super Record Steel (assume 2011 Steel Super Record is the same or very close): 658 grams
Campy/SRM Powermeter: 796 grams

The asterisk footnote at the bottom of http://www.campagnolo.com/jsp/en/groupsetdetail/item_guarSRST_catid_12.jsp wrote:* The nominal weight refers to the lighter specification among the available options.
...
The nominal weight does not take account of the sometimes considerable quantities of grease used in the assembly of the products.
Although this does seem to be saying that a 170 39-52 standard weighs the same as a 170 34-50 compact, which seems dubious.

Yes, as far as I know the weights should be pretty much the same. The only change I'm aware of is that they beefed up the rings on the Compact cranks a bit since 2011 to accommodate the greater force that the EPS front derailleur exerts on them.

For comparison's sake, my 2012 SR 53/39 172.5mm Ti cranks were 597grams.

I have this crank and can't imagine using any other. Super good looking, functions as you would expect and above all, it's been set and forget.
