Touch Pro Questions/Dilemma

[entwined82]

I've got a free touch pro coming to me but I'll have to pay $175 to cancel service with Verizon to use it with Sprint. I'm reading a LOT of negative stuff lately about the touch pro especially with regards to battery life so I have a few questions.

The custom roms that improve battery life are merely using the Juicy fix right? [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Battery]
"PollInterval"=dword:4E20 is what I am referring to. I was looking into Mighty Rom..how great of a boost in battery life do you folks using it see?

Also, will I be able to get a decent gauge for the phones life without having a carrier for it? You know, just using wi-fi and all that running apps and playing around.

I finally got my 6800 with Verizon to the point where I'm REALLY happy with the battery life. I have an extended battery and all registry battery hacks running and the performance is alright after a few tweaks..I soft-reset every couple days but its nothing too annoying. In my shoes what would you do? Will I be in a similar situation with the TP? Needing to run 12 hacks and put a battery twice the size of the stock one in to be happy with it?
