For a scope or a Labradar, I am not sure the pistol grip ball head makes sense if weight is a big concern.
I bought a pretty cheap carbon fiber China tripod and it has a ball head that would be good for a Labradar. For a scope, I like a telescope style slow motion control, leveling heads and full telescope style gimbal type alt/azimuth mounts.
Orion makes a small slow motion control for about $40 which is pretty cool and will let you aim the scope without shaking it too much.
For more like $150 you can get a Kenko mount which is pretty awesome but uses a Vixen dovetail, it's pretty bulky and not terribly light. I have one on top of an old Manfrotto leveling head and a nicer carbon fiber China tripod but it's going to have a fairly large spotting scope with Binoviewer, a binocular LRF, a red dot spotting scope and a Kestrel.
You can get away with a lot less if it's just a spotter.
I also bought a cool folding three legged stool to use it while seated which can let you use a shorter, lighter and more compact tripod.
