Another rental carpet question !

[Mohammad Sheatt]

I went through several threads related to carpet in rentals and would like to ask this question.

I have a 1300 sf SFH I am renovating to rent

Downstairs I am putting Vinyl planks

Upstairs there are 3 bedrooms I am thinking about carpeting 

I looked at HD and Lowes for carpet

my questions are 

should I put a 16oz carpet or a 25 oz carpet given the difference in price is around $150?

would a higher oz carpet last longer and hence justify the little extra cost? or are they both going to wear off and have to be replaced at the same time any way?

Is lighter or darker colors better for rentals ?

what other pearls do the experienced landlords here suggest?

Thank you
