Not if you do it right. Speed chain is great for loading, storing, and release.
Feel of lag, pivot, rotational componants, many more.
Speed stick has no clubhead feel, sweetspot feel, long....don't like it.
Homerson is correct. The speedchain does not differentiate betweeen contrasting teaching methods because it follows any movement your hands and arms make. Therefore, you are just making those golf specific muscles stronger and faster. It also is the only device I know of that meets the 4 specificty laws of training for speed. A hitter or swinger would benefit.
