Hi Guys I've mastered ATM i can do about 20 in a row and 6 np. Can you give some tips for Luki ATM please 
how fast how clean are those - record them and watch
p.s. my friend mastered g atm first and then latm
he practiced such thing as atm-hatm on side np - that is - you do full atm but don't land it on the neck - go on and do half of the atm and catch it on the sidehead (its like 1.5. atm on side np) - good drill - hard to pull though - it requires speed - record it - to see how it looks
srry it is hard to explain - i tried it myself and felt i'd rather work of other things - cuz it's mad hard
