Chris...I grew up using all kinds of cable handles and personally I think they are fine, adjustable (easily)
BUT...I read and followed a lot of the Bias Handel threads and solid LIGHT weight threads... and decided to try a PA Randy Smith Hard point version with Hello Kitty Clips to set neutral
Trust me I am a hack flyer with no ever notion of even entering beginner contest....BUT ALL my Hot Rock Cable handles are now in a bin to be sold or trashed some day
I found that on .35 engine 28oz and larger planes, the Hard point handle has a LOT more hand feedback that I assume is dampened in the various cable handles
There is no reason to no like the easy to adjust cable handles... I just found that the one hard point I tried was A LOT better...for me
Side note
This year I am focusing More on flying and to that end I plan to set up each of my 5 flyable planes with their OWN dedicated lines and Handles
