Are there any modern plastic inner ring hybrids; for example, like a Protostar? I already know there’s a ton of outer ring hybrids but couldn’t think of any inner ring ones.
Started thinking about it when I saw the Atom Smasher was a successor to the Protostar. I wish they stuck to the inner ring hybrid theme and just got rid of those spacers.
On the opposite end of the price spectrum from the Protostar there’s the Mowl X. It’s a polycarbonate Mowl Q with an inner steel rim. I can’t really think of anything else though.
Not quite inner, but like mid-body, is the YYR Triad. To shamelessly schill, I have one for sale from a lucky box if you’re interested.
sOMEThING Addiction and Sure Shot. YYF Arrow Pro and Overthrow. One Drop Rally. Da Capo was an inner metal cap so kinda along the same lines.
The protostar is mentioned in the OP 
Yes I noticed that the moment I posted lol that’s why I deleted my reply
Something Addiction is available almost everywhere and IIRC it fits that bill
