If you take a look at the rambo(top) picture you will notice that dominator and shag play one way and rambo and method play a different way physically.

If you take a look at the rambo(top) picture you will notice that dominator and shag play one way and rambo and method play a different way physically.I'd say about 70% of the community plays the way dominator/shag play but if you notice how rambo plays one could assume that him placing his arm on the table makes his wrist aim more stable.A more steady hand.

It is a little bit slower but when I asked rambo about that he said "Well...I'd rather be able to aim consistantly on LAN no matter what the table or chair setting than be completely fast with my arm movement"most players play with low sensitivity and fast arm movementI personally use default windows and 2.3 sensand so does rambo and storm What really drew me to the conclusion that having my arm steadied on the table would make me more consistant as a player is when I noticed that in the finals of CPL fnatic vs MYM, 

the top 3 most consistant players for those two teams all did the same thing physically which is what you see the guy in the stripe shirt doing (thats REAL from mym)or f0rest (in the pink hat) or tentpole (with glasses in the black fnatic shirt)
