That's a good question. There are some who claim that a balanced bootstrap is better for all situations. There are no major drawbacks to using the balanced bootstrap, and it would be a better method if the data contained an extreme outlier or high-leverage point. So, yes, I think you are correct. If you use the balanced bootstrap, you must use the OUTHITS option in PROC SURVEYSELECT and cannot use the FREQ statement in PROC REG.
