it's not so much a yield gaining thing here.. for me, in my area giant colas would just be stupid; an invite to rot and premature harvest.
i top, lst, and supercrop my girls to keep them as short and bushy as possible (though i kinda failed this year
) and to create more smaller cola's, as they will likely make it to full bloom.
if you're in north america, i hope you're not planning this, it's likely too late now.
as for lollipopping. there's benefits either way IMO; (but i'd definitely not go as far as indoor, i'm just talking removing a few lower branches)
if you do it, you'll cut off smaller producing lowers, but more benfitial OD is the added airflow you'll get with the removal of dead low stuff that could also cause mold/rotting issues.
to leave it; i like to because i grow in pots.. that low growth is shading the pots a bit.
i dunno how much it really helps, but in my mind it's keeping the sun from beating on their roots as bad.
