Please reccomend me a custom rom for sm-705 lte (an working lte)

Hi friends, im almost new here... have a sm-705 lte and want to flash it with a custom rom...

But im seen, not sure, most of them dont work lte data....

I use my sm-705 lte 8.4 as a phone (yes im crazy :o) and want a good custom rom without loosing lte and phone calls functionality...

Anyone with same phone can say me your experience with any working rom?

thanx in advance...
