Good Morning, Stephanie,
I concur with the sentiments expressed above, but would add a couple of points. First--Hewes reels were (are?) sold in the US under the King Concept brand, although the "Hewes" imprint is still on the reels. Second--in past postings, I have also advocated using Hewes reels. I continue to do so, at least in 35mm. The loading is virtually foolproof, and the reels are sturdy enough to be a lifetime investment. Recently, however, I spotted some Hewes 120 reels for sale on E-Bay. I don't have any of those and was thinking of bidding, but when I looked at the accompanying photo, I noticed that Hewes apparently uses the Nikkor-type "springy-thingy" at the reel center. I have found that method of anchoring 120 film to be slightly frustrating in use. For 120 I highly recommend using Kinderman reels, which have a very positive puncturing pin to anchor the film and whose high quality is essentially the same as that of Hewes. Kinderman tanks and tops are the way to go regardless of the reel type, but, as David says, the plastic Kinderman top is where the main emphasis should be. Kinderman stuff is practically being given away on E-bay these days.
