After cleaning the BRFSS data for sample ranging from 2005-2015 I need to append the data. But, before doing it should I use the following command or should I use the _finalwt option while running a regression

use brfss2010.dta, clear
svyset _psu [pweight= _finalwt], strata( _ststr)

Right now my regression looks like the following . One confusion is what I would do post-2011 for weighting where _llcpwt is available which means besides landline cellphones were also introduced for interviewing respondents ?

reg insured male age_18_34 age_35_49 age_50_64 highschool lths bachelorplus white black asian income_group [aw=_finalwt ], cluster(statefip)

Thanks in advance.
