I suggest you forget the straps for now and get or make a carrying bag of strong, medium to heavy weight nylon ripstop, with a string closing mouth strap and, a one and a one half or two inch, adjustable strap, with nylon "D" ring and buckle or Velcro.
The bag is;
1). easier to carry
2). allows wet or muddy, grassy tripods to be carried without spreading the mud and vegetation on your cloths, tent, car or floors
3). keeps prying eyes from easily seeing what's in your car or room and hunting additional camera kit
4). Has room for a monopod, umbrella or gun stick for long or heavy lens support
5). A towel or two for clean up and dry ups, which could be wrapped around noisy tripod, etc.
6). Makes the tripod easier to carry, and keeps legs from being unmanageable and spreading out and hindering you, or catching branches, vines, or wired/cables you're passing through.
A clothing repair or alterations shop or a luggage repair shop can make up a strong tripod bag quickly (once they start) or ask family or a friend who sews to run one up for you.
It's an easy task.
