I have had my TM springs for about 4 months now and love them. Direct fitment is so nice. No mixmatching of parts to make it work. What surface are you guys running on the Visalia track? It's cool to hear of others in cali using TM cars. Noone down in San Diego even knows what they are when they see one. Just, they can't stop talking about the layout of the chassis. I tell em, then buy one. Alot to be said about having "spare parts" available at the track.
