I'm not sure if you're getting a lot of feedback so I'll give you some.
The first time I flashed v3 I used the De-Sense tool shortly afterwards and it worked fine at first but for some reason my data speeds came to a crawl (1x) and the back felt really hot. So I re-flashed v3 and did not use the De-Sense tool and have had nothing happen since then.
I have actually flashed v3 a few times testing out different setups. I'm very happy with using the 5x5 3D launcher and have even had good experience so far with using the full sense version. Like I said, battery life is a little worse but not by very much.
