Since the teeth have the angle marked on them, I assume you mean it would be difficult to hold the file in the right place to file the tooth correctly without a guide?It would take good hand to eye coordination and good vision to be a candidate for not using a guide.
The ones you posted back in post 54 are worth trying. s93g and sp33g would be the ones. The top plate is visible during filing.
