My collies arrived today!.... very fast delivery!.. i'm confused though, why do we order HTs and end up with a TA Technix box, red springs instead of blue?... also i'm confused, wanted to check what the drop range was, the thread is 170mm, i'm guessing the extra mm is taken up by the helper springs hence why the max drop achieved with them in would be 120mm. i was worried that becaus ethey were TA technix they would only have 80mm drop... sorry does any of this make sense?
