I think it's thoughtful and insightful that they made the 8W with a top that would accept and EGO.
The more versatile, the better - at least from the manufacturers stand point; and quite a few users I bet.
I don't use EGOs so I don't care. I'd prefer a standard 510 short cap with a nice double adjustable screw just like the Chi You uses.
The single screw for the top cap on the Ehpro Shipwreck sucks. 510's are not all the same: one of my tanks will sit flush, where some closed end rba's will leave a big gap; having to switch that screw and readjust and keep the different batteries from rattling is a pita.
I wouldn't be surprised Sigelei was already making a shorter standard 510 only top cap for the 8W right now - as we type
I really do hope they are reading this: I wanna ChiYouDoubleScrew! lol
Nice and big so they can see.
