Which radio works best on VZW XV6800?

[veedubguru]

Ok, I'm currently running the following versions on a Verizon XV6800.....

ROM Version: 3.49.NO2.5066 from no2chem (WM6.1 Build 19231.1.0.4) (great rom by the way, but when I downloded it was listed as 5067???)

Radio Version: 3.35.04

I've noticed there are higher versions of the radio scattered about, and I've been wondering... which radio version works best for the Verizon network? I would try them one by one, but calling and being on the phone for an hour for a new A-key to get my phone back to making and recieving calls kinda sucks!

So I'm looking for words of experience on this. Which has worked best for you Verizon users out there? GPS locks quickest, and best signal and evdo speeds. (I know sometimes you can't have it all.) And any links to radio updates would be great too!

One other thing I'm wondering is about updating the radio. I know when I went up to 3.35, my phone wouldn't boot past the HTC logo until I flashed the stock VZW rom to the No2Chem 5067 rom. So any breif ideas as to what I might run into while updating to any suggested radios would be appreciated.
