what gear for my 97 cobra???

I have a mostly stock 97 cobra.I am getting ready to have my rearend rebuilt,and was wondering what to replace the stock 3.27 gear with.I already have a set of 3.73's to install,but have heard i should go with 4.10's.That sure does sound like a lot of gear to me.Please let me know what your experiences have been with gearing a 4.6 DOHC.
