Borrow someone's for a test.
I use Parma Econos 35 OHMs here on my track. I did add a Pot so I have adjustable brakes for various classes of cars we race. Others use Slot.It and PM ones. I do not find a big difference using theirs on a short track. I think it is more to how you squeeze that trigger. If anything replace the finger and upgrade the hand/eye co-ordination.
