[Zope] Stable combination of zope2.7/python/apache?

I am currently running Zope 2.44, Python 2.13, and Apache 1.3.22 on a RedHat 8 server which is pretty stable. I want to upgrade to 2.7 to take advantage of ZCTextIndex, as I want to have the ability to have exact phrase search capability and also take advantage of the faster speed. What is the most stable combination of Zope 2.7/Python/Apache? I had to use Apache 1.3.22 at the time because .23 and .24 had cookie setting and handling problems. Michael
