Sounds awesome! Just point me to the planet and I'll give it a go.
Sorry, I've been trying to OC my GPU, so I've spent a little time in "SAFE" mode in win10 to try and get anything else than a black screen after login. Caution Will Robinson!
The system was HIP 36601, and it was a moon of one of the planets called HIP 36601 C 5 D. HIP 36601 is quite a way from civilization, ~1.600 ly, so it takes roughly half an hour to get there, depending on jump range. It does have some goodies though: Crystalline Shards! You can shoot those and pick up G4 and G5 mats (very quickly). The good thing is that they only drop G4 and G5, and that there plenty of them, so relogging isn't necessary. Scan the moons and look for "Biological..." to find Crystal Shards. You can find the geysers looking for "Geological..." instead, if you should chose to go there.
I think you can find geysers closer to the Bub. From what I learned, fooling around yesterday, the moon (or planet) has to have very low gravity. I don't know how low, but it seems logical that the lower, the better. The moon I used was 0.03 G. Secondly, not all geysers are equal. They have to be pretty powerful to lift the SRV. The ones on the moon I tried were rather violent and had a loud hissing sound. Also they vary in strength over time. Just chose the biggest one you can find, where the steam coming out of it moves as fast as possible. I think I went up to about 7 km in a few seconds
Weeeee....
Once you are up there, the SRV maneuvers like a spaceship with FAoff, so it is not so easy to stabilize the thing, which is sort of what you want, because the descent is free fall only compensated by the weak thrusters of the SRV. I landed very hard several times, and tumbled over the surface like one of them Mars rovers encapsulated in balloons, but it wasn't destroying the SRV. Bring some mats for SRV repair, or mine them at HIP 36601. The system has everything but a truck stop.
Edit: HIP 36601 is very good for mining Crystalline Shards. You can find Polonium (G5), and Ruthenium, Tellurium and Technetium (all G4). All at moons around the C star (which is ~150.000 ls from the main star). It's well worth the trip, if you need mats for mat trading, and who doesn't?
Here's a video showing a SRV geyser jump:
