I don't think strobes will be supported for the TTL function.
You can trigger strobes (with a connector cable), but remote power level control and TTL won't be supported unless the strobe has a hot-shoe connector and implements a standard protocol (e.g., for Canon or Nikon) that the V6II is compatible with.
HSS is sometimes still available with strobes, if the latter allow to manually engage HSS. This works with some Godox flashes/strobes, for instance.
Originally posted by sqrrl I'm assuming this is with speedlights.
Yes, and they have to be supported by the V6II. The number of models (from many brands) supported is very useful, though. There are generic flash profiles as well as the model-specific ones, meaning that even a non-listed flash model may be supported after all.

I agree that reliability is an important factor. My V6 units have been 100% reliable as well.
I don't have much experience with the V6II yet. Early firmware versions had issues but with later ones I had no problems anymore during testing. Haven't used them much for real shoots yet, so I wouldn't be able to vouch 100% personally. There don't seem to be complaints from other Pentax users, so I'm not suspecting issues.
Originally posted by sqrrl I just run everything manual as i never know which camera I'm about to get handed.
I'm a big fan of manual control myself. I find it easier to use and it delivers 100% consistent results. However, TTL could come in handy for very dynamic situations.
