MIUI V5

I've been all over this forum for the past 2 days trying to find a solid MIUI v5 ROM for my phone- SM-G900T S5 on Metro Pcs, using T-mobile towers (boot animation says T-mobile also). If there's a link I've overlooked, please let me know! Yes, I am rooted.

I have previously flashed v6 MIUI for my device, but keep having problems with WSM tools and the never-ending bootloop issue, and would like to switch to v5, as I've read throughout this forum that the WSM/MiTools issue wasn't happening on v5. Correct me if I'm wrong, though. I am reading conflicting information throughout posts, and would like to check in with the more advanced users to steer in the right direction.

I came across a list of ROMs from Mega Unlimited site, and I am unable to post an outside link as I am new here, but I'm having trouble understanding which versions are okay to flash for my device.

I'm relatively new to flashing ROMs but I do a lot of reading through this site and others to understand what I'm doing before trying to just pile crap into/on to my phone. I don't like to post questions unless I keep getting confusing information, so please no snarky remarks, I promise I will be out of the way soon :o
