Zigg- Prepare for trans noise. That 1pc will transfer the tiny bit of play the welded has between engagements. It's not bad, but def a "wtf is that noise" moment. Good solid metal clunk.
Also- I'm curious what tires you're running and at what alignment. I didn't really notice any extra wear the months I was DD'ing mine with a welded
OP- Run a tire meant for rain. I.E. not a bald-dead-dontbecheap tire and you'll be ok. Rain is a matter of throttle control. Chirping didn't happen too much on mine, but it's about tire size and compound to whether it chirps, squeeks, shifts, or clunks.
Liveable- yes. Ideal, no, but livable. Can always swap it out for a standard pumpkin should you hate it.
