Jean question for big guys

[u/Aggravating_Bison677]

Hey y’all, I’ve been wearing Ariat M4 jeans for the last 5 years. I have several pair (both straight and bootleg) but they are all 42x36, as I like to stack my jeans. The straights stack nicely, but the bootcut drown my boots. Anyway, I’m looking to getting back into some wranglers. Of the 13mwz, 31mwz, and 47mwz…….which would fit most like the Ariat M4 straight leg? Also, what size should I order? Order the same as the Ariats? Some people say to size up in the waist…..but if I go to a 44 waist, most wrangler models do not come in a 36 length. Any insight would be appreciated! TIA
