Hi Trev999,
sorry for taking so long to answer, I just saw your post.
Right now I am using your V1 retarder since no other one works as good as yours.
Once in a while a car is rolling over the retarder, I guess it can still be optimized
since I only use 1 retarder per track.
I'd still like to test out if your V2 retarder will improve the hump and give you feedback.
I will send you an email, thank you very much.
