You'll enjoy them. The first ToW seems a little dated now but back in '84 it was the only book out there. I read mine from cover to cover dozens of times.
The other day I pulled it out and found the race worksheets filled in from my first race. Brought back alot of great memories.
See if you can find Nick's book, it applies more to street sport riding, where as ToW is mainly track. Both are great however.
