Playing with Probes: Guessing game.
BillyO:
The PP-90s I got with my 6074BC were grey too. They also did not come with the ground springs.
The PP-300s I got for my SDS1204X-E (well, "improved" SDS1104X-E) are black and did come with the spring grounds.
However, I'm not too impressed with the overshoot on them and there is no way to adjust it. I recently got 6 of the Pico TA-386 probes for $10 each from a surplus seller. They are a pretty big probe but I'm really impressed with their performance and I may just get another 4 of them for the little Siglent to replace the PP-300s.

My supposed 'Hantek PP-250' arrived. No Hantek branding on the documentation, documentation mentions PP/250 and PP-300. Black with ground spring.
The punchline is they sent it wrapped in cardboard to protected it. Specifically the back of a box for a UNI-T P05 probe. A probe that looks exactly the same as the PP-250 I received except for the sticker on the connector with the model number.
Although it's a 200Mhz probe, not at 250Mhz one. (I only really need 150Mhz so I'm fine).
So I suspect that is probably what the PP-300 listed above is as well.
Of course there's a good change they might be the same source that Hantek is using anyway. The PP-250's pictured on the Hantek site look exactly the same as the UNI-T ones. Although Uni-T doesn't make a passive 250Mhz probe closest are the UT-05 200Mhz and and UT-06 300Mhz probes so unless they made a custom order they are shipping below spec probes.
From my limited testing the rise looks much the same on both the grey PP-150 that came with the scope and the 'PP-250' I ordered from Aliexpress. The PP-250 does show more dips and rises not sure if that's the increased resolution or it causing increased noise.

Nice, those are like $65 AUD each.

I have a home made Z0 probe, but it's not made with very good cable. I guess I could try to make another.

You should change them, I also had bad wiring, because of them it shows me wrong data... By the way this was the cause why I lost several times here [spam link removed] because I didn't have the correct data and this interac casinos got that tricking me, but since I did this procedure - everything works fine and I am satisfied with it.
