I have Hewes, Nikor, Kinderman and a few unbranded 120 reels, and they all work the same for me.
I do not use the center clip - NEVER - on any of them. I just hold the end with my thumb for the first round and go from there.
I quickly found that trying to attach the end to the reel-clip just lead to disaster.
First I roll the 120 film free of the paper so the taped end is a the "beginning".
The taped-end then is where I start in the center of the reel. If that makes sense.
I have found that Paterson plastic reels as well as Hewes steel are perfectly fine for 35mm, but I can only comfortably use steel reels for 120.
