Need Advice - Weary of Flashing

[mfpreach]

Here is the deal,
When I first got the touch in Feb, I flashed the Rom to a WM6.1 release. I would experience problems like it randomly rebooting with the charger on and very poor performance. It turned out the device was DOA, i don't think it had anything to do with the flash.

I got another touch, and it was DOA also.

My question to you guys is, the Touch that I currently have is running the Bell Mobility OEM rom 1.17 , and everything is running perfectly at the moment. I Have had about 5 or 6 phone calls out of a few hundred freeze on me, but other than that no real complaints.

Is it worth flashing to 6.1 with GPS? Are the new roms and radios better than what I have right now. Do I run the Risk of having random hardware problems if I do this? I am paranoid since I believe I had a bad batch.

I know most people can't answer this question for me, and I am leaning towards, if it aint broke don't fix it. But if the new roms perform significantly better it may be worth the change.

Thanks!
