I've gotten hands on with the PA Rafa Origin, and compared with my Aeropro Drive, as well as compared with a set of replacement grommets.
Few things I found out. The mold of both rackets is pretty close to each other.
But here come the differences. Since I had an extra set of Aeropro Drive grommets, I popped out the RO grommets and tried to see where it can fit. The drill spacing throughout the entire racket is different between the two. I tried to swap the APDO throat grommets onto the Rafa Origin, and it was slight off, so couldn't fully push the grommet in. The side grommets spacing were also a little different, so could not be swapped. The spacing at the head guard of the racket was also different. if you take the RO head grommet insert, and try to fit it with the APD headguard, it can fit if the head guard holes are enlarged.
In conclusion, it looks like there is some differences between the Original Aeropro Drive, and this Rafa Origin. But it still looks like a fun racket to try out.
