DdDrRaGeX like something serious, I have the exact same problem and I cannot figure out how to revert back to my old style of playing. It seems like my tradish has gone out the window from me trying to learn to use arm with it and it has like no power and my right hand does this weird chicken flapping motion on every stroke I do, and I mean every. Even eights causes tension in my shoulder down and it forces me to do some arm in them, sometimes all arm. I just hurts and feels weird and I know its wrong. It probably has to do with my stick angles.

Any ways how can I fix that?

murray gussak broke down double stroke rolls completly.
at slow tempos you play 2 full strokes, then as you speed up youstart playing the secong by sqeezing the second stroke, and as you get fast(like where you are holding the stick down) thats when you bring your arms in, slightly.
i hope that makes sence. it probably sounded better when he said it.

no that sounds good, i mean, you always want to eliminate arm movement as much as possible. but there is a point where that becomes incredibly hard almost impossible and instead of taking the time to improve the whole line in how fast they can move their wrists together. it is easier to work on the amount of arm each puts into it...you know?

When I get rolling pretty fast, my forearms automatically kick in and they do most of the major motion (less muscle motion for more stick motion). My fingers move to handle diddle control/ quality. My wrist sometimes provides a little extra motion to help my arms out. My sticks stay straight (like an extension of my forearm) when I am using no wrist movement, but adding the wrist allows me to get vertical up & down motion (arm) and normal stick-coming-back motion (wrist). By "stick-coming-back motion" I mean the normal path like your stick would take if you played 8's at 9"-12" where your stick changes angle as it moves to and from the drum. Hope this helped.

You said you just started drumming "seriously" recently right. You may be biting off more than you can chew right now. Work on slow rolls then work up to it. use the technique that is needed to play fast "speedo" rolls while playing slow rolls. in other words practice the fast technique slow. You will better understand what it takes and your muscles will be able to memorize the motions easier.
