Dura Ace 7900 front derailleur issues

thebigman

im upgrading from 7800 to 7900 and after installing the cable into the FD im having shifting issues. If i tension the cable the downshift from big to small seems quite 'agressive'. If i loosen it so there is a bit of slack in the cable, the downshift is better but i loose the trim function in the small ring..all limit screws are correctly set up. anyone had this problem?

thanks

The downshift is quite aggressive or at least is always has been on the 7900 that I own (which has been on a couple of bikes now and reinstalled a few times).
