Your point regarding use of a single stick is a valid one that few would argue with. However, the issue I have with such multi-legged sticks is I have real need of a stave-like stick of a height associated with the alpine variety to enable me to negotiate the precipitous terrain that is my stalking ground.You'll never get the steady support that quad sticks provide using a single stick so it may as well be left at home and you instead use your bag as a rest, a fencepost, tree or other steady. I carry a compromise which is the lightweight telescopic Vanguard tripod with tracking V neck support. I find that sitting for the shot I can find a steady braced position with the tripod to take an accurate shot to 150 yds no problem, but further than this I'd prefer quad sticks. If using the telescopic carbon ones you can tether them after use no problems to your roe sack in the folded position and won't know you're carrying them. I used to use the garden cane "monkey sticks" but found that for stalking, they were too bulky and awkward if having to drag or carry deer, hence now exclusively use the Vanguard which is a very good compromise, especially if the head is replaced with one that provides a better shelf for the forestock. However if I had the spare cash and could justify the spend I'd be using carbon quad sticks.
I’m therefore still looking for a set of sticks that when not deployed lend themselves to the above use and will take my body weight when leaning into them. To date none are even tall enough let alone of the required strength.
