I can't speak for Tim, but I use both the roll tester and an

inclined track for my cars. As Denny Anspach has said, the roll
tester is a very good indicator for determining how trucks roll. His
criteria is similar to my experience. One additional comment,
cleaning the track with isopropyl alcohol can have a positive effect
on how a truck rolls. Once I have trucks that I consider "tuned," i
apply the trucks to a properly weighted car and put it on my incline.
My test track is six feet long (on a plank) with a short incline
about one inch high at one end so that about five feet of track is
flat. The other end has a piece of foam rubber to act as a stop (no
damaged couplers yet). I am satisfied if the car reaches the end, but
a good rolling car will rebound about a foot or so. A lightly
weighted car does not perform as well. When not in use, my incline
sits in a corner taking up very little room.
