I agree, you need to work on adding more speed to the combo. If you struggle making it faster I suggest practicing skin the gerbil until you can do it fast. That will help you to get used to moving the yoyo around quicker. Then learn one of the simple kamikaze mount speed combos on YouTube. Practice that until you can do it fast. After doing those two things you could work on making your combo quicker.
This is just what I did when I started learning speed tricks. I don't know how much experience you have with all this stuff, and I don't know what "ner" is either. I am just giving you some advice, and am not trying to be bossy. Good luck.
