Yes, Bobo, that is typical for macro action shots.
I find that my Lowenpro Mini Trekker is a well balanced backpack which doesn't really hinder me too much. But by the time I start shooting it only contains a spare lens and a selection of lightweight items.
Although I often prefer to remove it and place in the shade to prevent my snack and water bottle from getting too hot if I am concentrating on working for a while in the same area.
Once everything is set up on the tripod, I keep it that way unless I am walking a fair distance with little chance of finding anything worth photographing. Just fold the legs together and tuck under my arm. A bit like the way a farmer/sportsman would carry a shotgun.
Moving a tripod around in dense undergrowth is a bit of a knack. I find that the best answer is to keep the legs fairly short and close together. Use the centre column to gain height rather than extend the legs by using another segment.
Completely the opposite advice for landscape photography; but in that case, you usually have plenty of space around you.
BUT VERY IMPORTANT - This will make you rig unstable so extreme care is always needed. I usually keep a hand on my tripod all the time. Which is another reason why a fairly fast shutter speed is needed.
