I too agree with Erock.
If you can do both (well) then that would be great. Personally I vote for off road if it has to be one or the other.
Its obvious that you are very passionate about what you are doing and that you truly care about your racers/customers. Everyone has been very good about making any new comers &/or beginners feel welcome and even offering them some help & advise. IMO As long as you continue in the direction that you are currently going I am pretty confident that you will be successful either way you go.
I have very fond memories of racing on your oval track & off road track back in the day, on Shawnee drive, as a very young teenager. Looking back on that, I am shocked that you put up with us!
