Any recommendations or pros/cons on best wood to burn?

I’m 6’ 6” and looking to purchase my first “beginner” sauna setup. I’m leaning toward a sweat tent but my biggest concern is my height. I’m also a large 6’ 6” built like a NFL lineman. Space is a necessity. Looking at purchasing the XL model so me and my wife have plenty of space. She’s 5’ 1” so no real concerns there. I tried some of the other cheaper brands and they were all too small. I am able to hunt out of hunting blinds which originally brought me to the sweat tent. Any recommendations in regards to my size? Would the XL be sufficient for my size?
