I built a rom for my Verizon Touch Pro using raidzeros kitchen.

Idle I usually sit around 20meg, more than enough for the majority of what I do. It does require some sacrifices but, for me, it is worth it over the stock rom.

Here is what I currently have:

sys/xip: 28011
Manilla 2.1 - 2.5 will work but brings my memory down below 10meg. Don't like the MMS issues ether.
8mb page pool
No Dialer skin. Saves about 10mb depending on the skin you would be using.
IE only for browser. I know I am odd, but I prefer the version in 6.5
Removed iContacts and Fingerboard. No need for ether and saves some memory.

Been using this rom for 2 weeks or so and it has been very stable and does everything I need it to do.
