Here is my first review. It is not of a Yo-Yo so I hope this is in the right section. If not I am sure the mods will move it.
I have read many posts saying that a bearing does not make a difference. Sure, if you are great you can do any trick on any yo-yo. I saw a video of someone doing spirit bomb on a 75 year old wood yo-yo. It was darn impressive. But personally, I do feel that bearings make a difference. Extra spin time allows the inexperienced (like me) time to learn a difficult trick.
I would like to say that I have not tried any non-stock bearings other than this one, so I really have nothing to compare it to. I have read that the One Drop 10 ball bearings are great. And a few others get good reviews as well. So keep this in mind while reading what I have to say.
I bought a Terrapin X Wing S/C center assist C size bearing a week or so ago. According to John (the seller and I am assuming maker of these bearings) this bearing should play dry. It should never be cleaned with lighter fluid or lubed with liquid lube. He has given each of these bearings the “Terrapin” treatment. I am assuming this is a form of dry lubricant treatment. If it gets dirty he recommends removing the shields and blowing the bearing out with compressed air. This method works great as I had to do this.
There are other reviews of this bearing out there that talk about how the center assist is sort of concave. It is not as deep as the other bearings out there and allows the string to still move and not bind up. I can’t speak from experience, because I have not tried the other bearings that are concave.
So, my review portion of this review. Eg: my opinions. This bearing is amazing!! I originally placed it in my Dv888. It supposedly comes broken in, but I did not notice how awesome it was for a few days. I carried it in my pocked a few times and got something stuck in it. This caused it to become loud and responsive. I took off the shields and blew it out with compressed air as recommended. Once I did this it was like a whole new bearing. It played like butter. I can’t feel it spinning on the string. It is not loud (to me) as I have read in other posts, but not having played the 10 ball I can’t compare it. It seems quiet to me. I recently bought a String Theory Remnant 2 and they come with a C size Terrapin treated bearing. The bearing in the R2 is different from the ones John sells. It is “Terrapin” treated but does not play quite as well as the one I bought from John. Earlier tonight I exchanged bearings in my Dv888 and the R2. I must say that my R2 is now probably the best Yo-Yo on the planet. It is my first throw that cost over $44 so take that statement in stride. The bearing cost a bit more than others that I see. I paid $25 for mine on his ebay page, but to me it is worth it. Sure it now makes my R2 a $125 throw, but like I said, I think it is probably the best Yo-Yo on the planet.
Summary: If you are thinking of buying one of these do not hesitate. John guarantees every bearing that he sells. To me this bearing is awesome, but like all reviews this is my opinion. His handle on this message board as well as ebay is FJH123. I am sure that if you message him he will be happy to answer any questions that you have.
I am sorry that this does not cover any technical specs that surround this bearing, they can be found in the other posts about this bearing. I just simply wanted to profess my love for this bearing. I will be buying more as soon as I can afford it.
