Yes, I have a V2 Piccolo and the Piccolo Special Edition. I find the FOCS smoother than the Piccolo OC and both are equally efficient.
Hard choice
When I shaved for the first time with an open comb. My next thought was. I will never shave with a closed bar again. Open combs manager lather in so much as leaving lather available for the follow up or a little extra buff. I wouldn’t try OC for the longest time I thought they looked too aggressive. Nothing handles lather better than an OC. Lo Storto is based on the Grande OC. I have both. I was using the #4&5 plate on the Rockwell when I sold it. Open Comb delivers more comfort to my sensitive skin than closed bar ever did.
I also use R4 and sometimes R5 with the Rockwell 6C.
Since you have both, do your prefer the Grande OC or the Lo Storto?
