I would reckon your tripod is fine for lenses up to a couple of kilos or so. The strength ratings of tripods for me are pretty meaningless - it's all about rigidity and how its being used. Any issue with your soligor 450mm will be due to its length, not weight, its not that heavy - what I refer to as bendy ruler syndrome, an inherent tendency for a long thin object to wobble and vibrate. You should check out some of the u-tube videos discussing things like weighting the tripod.
I customise plates for long lenses (this pic here shows the use of a cheap macro rail on the heavy and way out of balance tamron 200-500mm) so I can get them balanced - counters sag and wobble. However one counter point is that shutter/mirror related vibrations are best militated against by mounting the tripod at the camera - locks the camera down. If you suspect camera related vibrations then you can get tricky with two tripod or tripod + monopod set ups, dampening with sand bags etc

Yes the head unscrews exposing a standard 1/4" thread post. Not sure why the reviewer says its fixed, it wasn't on both the examples I've seen.
I actually like the one-handle head, it's beefy and solid and smooth IME, with only negligible sag after aiming and locking. More control than ballheads esp with larger lenses IMO due to "tipping factor" (the more you tilt the lens the more out of balance it goes). But doesn't have a QR plate of course. I'd only swap it for a gimbal.
