for the rlss its a 180 degree turn to either open it or close it , so the tuning is fast but hard to pin point. the pipe its self turns easily
the skimz is going to take alot of full 360 degree turns so can easily be tuned,but slower on the off and on, the handle is also easier to use then the pipe of the rlss which is often covered in salt or something anyways lol
