Thinking back to what I’ve had to silicone, it’s been really mostly “western” and “european” yoyos. CLYW’s and MFD’s, YYFs, YYJ’s and other stuff. However, I’ve siliconed SOME Asian stuff, mostly Aoda and Audley, and they are playing amazing. I haven’t done my Magic yoyos yet.
I think part of it is the product, but you’re using the same product. Is yours old or new? Are you scraping out the excess? Are you removing the bubbles? Are you waiting a full 24 hours for the silicone to cure? This lack of waiting seems to be the biggest problem area.
Most yoyos seem to use a fairly standard depth.
I agree with not wanting to buy pads, but you may have to limit yourself a tad since some are so thin that you either have to use pads or send them out to have the response recess deepened.
If your yoyos are metal, clean out the recesses with mineral spirits, acetone or alcohol and completely get rid of any adhesives left behind. If plastics, DO NOT use acetone as it will “melt” most plastics.
I think the only time I had a problem with flowable was my DM2, but I was using a super rough string that was just eating the response to death. The other was my Fiesta XX, which based on how much pressure is placed on the response pad, one tore out after an hour of heavy play. I also chalk that up to the body being celcon and the silicone not sticking well to it. So, because of that, for certain off-strings, I’m going “pads only”, which will most likely be my celcon and delrin off-strings. However, I will try to silicone an off-string when the time comes just to see if it will or won’t work out well.
