Well, I’m planning to buy one this Christmas, But I just want to make sure.
So I want just to remain the Response System Hybrid, And change the bearing to KonKave. 
Does it have also Tight binds even it’s Hybrid? (Don’t reply and tell me to get a Hitman okay? :D)
Is the O-ring will rub or touch the string even it’s in the center because I’m getting a KonKave or it wont touch the string?
Yes, it has tight binds.
No, it will not touch the O-Rings with the KonKave. However, with multiple string layers it may.
No matter what kind of bearing it is, if there are too many string layers it’s gonna start touching the sides. Also with a Konkave the binds will be more prone to slipping.
the DM also has an adjustable gap.
dm is a good yoyo to finish up to advanced part 2. it will perform exactly how u would want it to but if want id go with a center track bearing it will keep multiple strings to the center . but whatever u do there will always be some string touching the side ;D
you could always silicone. But i played with o-rings for 5 months and it was fine
It could also finish up ever other yoyo trick in the world…
