I too have been attempting to get a satisfactory response ... here is todays email (10/04/10) ... not much help but we are getting closer;
To: CS
Benelli 81044P Raised ComforTech Gel Comb Insert.
Will this product fit on the Vinci?
CS Reply,
That comb will fit, but it will not be a perfect fit as the Vinci comb is slightly different. We will have combs for the Vinci, but that won't be until after the first of the year.
I guess meaning sometime in the 1st half of 2011.
