[any name will do]

this is what i had as a kid and i'm starting again after many years. i'd like to have two of my favorite
2 lane courses based on real F1 courses joined by my personal build. when i wanted to race one of the F1 courses exclusively just exchange
a few tracks to separate the F! course. here is the rub. i'd like the courses to feel like they were designed by aurora in the mid 60's-70's. imho back then 
9 inch curves here used mostly with 12 inch after. the superinternational set is loaded with 6 inch curves. 
or maybe have 2 popular courses back in the day that don't have to be F1. 
anyone have track designs from that time?  maybe get the afx giant track with all the 9 inch curves would be better. 
with either one buy a track pack or two.
