I've been slow to come around to passthrough, but I will say that it has gotten MUCH better. The recent Ashley Alexander release was the best all around PT release I've seen to date on SLR. The ONLY thing missing right now has to do with the functionality of the DEOVR app.
The biggest hurdle to enjoying a PT video right now is getting the video lined up correctly with your body, and being able to adjust it quickly while you're "servicing' yourself. The controls for doing this in DEOVR are cumbersome and it takes way too long, killing the mood. Heresphere, on the other hand, allows you to translate the image quickly by pulling the trigger (on quest) and setting it where you need it. It's unfortunate that I have to download SLR videos and stream them (or sideload) just to view them in Heresphere. If DEOVR would just add the option for the same type of image manipulation, it would be a huge win for the passthrough format on SLR and DEO.
