What airplane and what is your flying skill level?

Nosehevy is safer than tailheavy. A nosehavy airplane's controls will be a little "sluggish" A tailheavy airplane will be excessively touchy.

Its bettr to add the weight (as far forward as possible) to get the forward balance point for test flights...then adjust moving the balance toward the rear by removing weight. If you start off too far back... you won't get the opportunityto adjust it... you'll just have the opportunity to fill a garbage bag.
