I pair them with a heavy aluminum Gitzo professional-quality tripod out of the 1980’s to 2000’s - also one of the best values for a tripod that won’t be carried.
If it says “Studex” it’s a 300 size and will be steadier than any new cheap tripod - maybe 8 lbs. The “Pro Studex” is 400 size and is the preferred size for stand up spotting in most of our family and is more like 10 lbs. The “Tele Studex” are the 500 series big boys around 12 lbs - wind hardly makes a difference with this one.

Art Wolfe used to use a 400 series aluminum tripod before the carbon fiber ones came out, to take many of his iconic wildlife shots. He also liked the big 55mm Studioball head, which is now like $100 used.
