Sprint HTC Hero :: Exchange Support - Sense V.s. Nonsense ROMs

I have rooted 2.1 on my Sprint Hero. So far I have tried Fresh 2.3.3, Darchdroid 2.7 and PureHero 2.3.I rooted for several issues, most of which have been solved, but my number one issue seems to still be haunting me. Good corporate exchange support! Sense based ROM's (Fresh 2.3.3 and stock) support Exchanges security policy and force you to enter a PIN, but bring up the keyboard. My company requires number in the PIN and therefore I have to switch to numbers and enter my pin on a keyboard. I can no longer chew gum and use my phone at the same time. Nonsense based ROM's (Darch and Pure) don't require the PIN and allow me to use a pattern security on my phone, but they don't let me overlay my exchange calendar onto my phone with my google calendar. They only sync mail and contacts. Hope this is where I am missing something. This is a deal breaker for me since I have google calendars for everyone in my family and exchange for work. Got to see them all in one place to be where I need to be.I have tried Lockpicker on the sense ROM's, but then I have no phone security. I have too much info on my phone to go with no security, but I don't want to quit chewing gum.Any suggestions? Is there ways to pick and choose some of the features in sense?
