For the a good entry-level kit, most companies opt for UK heads. Many drum companies will utilize both models across various levels of quality in their production. Though not as good as Dupont Mylar film, it is far better than any of the cheap, local supply of film in China. These heads are designed for the entry-level kit and use a Korean film that still has good sound and durability features. Remo UK heads are also made in the same factory in China. In terms of sound quality, the UT head is excellent due to the high quality film that we use. The aluminum hoop is folded over a steel ring that is inserted in the U-channel to hold the film in place. Whereas the US head is made using a poured channel technique, the China heads are crimped. The difference is in the construction of the head. They are made using the same Dupont Mylar film as is used on the Remo USA WeatherKing head. The Remo UT heads are made in our factory in China. This was taken from another forum that I stumbled across when trying to find out info on them a while back: But FWIW, Winston is on the money as far as i can gather. on the specs and any comparison to Ambassadors or Diplomats, out of the equation. on the UT/UK's.other than stating that the heads are crimped into the collar, they leave any info. Remo seem to be notoriously tight lipped when it comes to info.

Personally, the first thing I would do with a new kit containing stock heads such as Remo UT or UK, is swap 'em out. I'm not saying a drum can't sound good with them on, but I'm an avid believer that it'll sound even better with a decent head upgrade. The are both vastly inferior products for mine. However, I have a foot firmly planted in your camp.UT's/UK's.no difference in my book. Some guys like 'em and if so, that's fine by me.
