I've just kept a slowly devolving set of fulls:

$Conf{FullPeriod} = '6.97';
$Conf{IncrPeriod} = '0.97';
$Conf{FullKeepCnt} = [ '8', '4', '2', '2' ];
$Conf{IncrLevels} = [ '1', '2', '3', '4', '5', '6' ];

That will keep 8 weeklies, 4 semi-weeklies, 2 monthlies, and 2 semi-monthlies.  
That means my oldest archive will be 40 weeks old.  With pooling, I find I 
really can store very long archives going back.  But I rarely need to get a 
file exactly 38 weeks old, when 32 or 40 will do.

Regards,
Tyler
