I remembered before that my DLs were really very obvious, until I worked out a way to make it look more natural. It even helped me do a perfect TL and now it almost goes unnoticeable even by the most scrutinizing viewer.
Now I've learned to abandon the other "fancy" sleights that I have learned (e.g. Clip Shifts, Hypnotic Cuts, etc.) for more natural ones and those that could be done slowly. I favored those, since in this way I could focus more on the presentation which is what magic is all about.
I'm not saying that we should all go for self-working and no sleights magic tricks, what I'm saying is that when it comes to sleights, the best ones are the ones you are comfortable performing with.
