Don't
quite accept your excuse that "very few instructors are capable to help in this respects"... be honest - it's a money issue, right?!
At the end of the day you are the one risking your life so just ask yourself whether it's not worth paying a few extra notes for a suitably rated (but more importantly
type experienced) instructor to travel to your strip and check you out next time.
The cost will probably be less than your funeral.
VFE.
