Duncan yoyo's are a brand of yoyo toys. A man named Duncan was the founder of a yoyo company that he had purchased and then sold his yoyo toys. They are a famous brand.
The Duncan Butterfly is valuable both in price and in performance. It has a butterfly shape for forgiving yoyo play, and it also has a long spin time for string tricks. It is an ideal skill toy for the intermediate player.
It can spin pretty fast. On impact, it can break a lot of things, including the yoyo.

because they have more advanced and better quality yoyos
Yoyos are classified by shape and the 3 are: 1) "Classic", also known as "Imperial" - These have been around the longest and include the Duncan 'Imperial', Duncan 'Speed Beetle', and the Team Losi 'Da Bomb'. They are best for looping tricks. 2) "Butterfly" - These are probably the most popular today and include the Duncan 'Butterfly', Henry's 'Viper', and Yoyojam 'Spinmaster'. They are best for string tricks and long spin or "sleep" times. Really complicated string tricks are almost always performed using a butterfly shaped yoyo. Butterflies are not considered to be the best starter yoyos. 3) "Modified" - These have rounded edges and are a good compromise between imperial and butterfly shapes. Good examples are the Duncan 'ProYo', Yomega 'Fireball', and the Spintastics 'Technic'. They loop well and are better than the imperial for string tricks. The modified shape is also considered to be a great beginners yoyo. Many other factors come into play such as materials, axel construction, weight, size, etc, but these are the 3 shapes, or "types" of almost all serious yoyos.
You add a ball bearing to the axle.
yes
depending on the axel type, a butterfly yoyo can sleep anywerefrom five seconds, to five minutes. my duncan butterfly sleeps for about twenty seconds, and my glow-wing and freehand for about a minute and a half, maybe perhaps longer.
a wheel and axil, as the yoyo will spin around because of the string and the axil located in the middle of the yoyo.
Although the yo-yo was a popular novelty item as early as the 1800s, Duncan was the first company to capitalize on it as a toy. The Duncan O-Boy was created in 1932.
