I understand that you are in the phase of building your cigar stock – we all have been there.
It is a good decision that you bought some older cigars for allowing younger to get properly aged. If you will continue doing this you will have sooner than you think great stock of cigars, mixture of aged and new ones.
There is no reason not to smoke older right away; maybe you can leave few of them for comparison with younger/different cigars which you will accumulate in the process.
