I think they left turbo out of the cycle because someone here convinced them to do it.
I like the instant turn on or shorter delay .3 sec. and hidden turbo plus clicks to lock out. I’m a little skeptical of removing the mode memory though. I just worry that once Sofirn makes the driver changes, they won’t make any changes again if the light becomes annoying to operate. There was a lot of issues with the first batch of SP10A. The resistance of the electronic switch spring caused the light to not operate when nimh or aa batteries still had more juice left in them. The went to a new type of electronic switch button but it killed the feel of the side button and it gave the light lower output. I tried to convince them to alter the driver and go back to the original good click side button. They said they have changed the driver so shall see how it performs now. I kept trying to get them to use a berrylium copper tail spring because I saw even better output with a spring bypass.
