stamp question

I posted this on 03 board but meant here so here it goes:

ok here's the deal-- my invitations are going to be stuffed on sunday and
we went to the post office to weigh my invite.
It is going to cost 83 cents for the invite and 37 cents for the reply.

My question is this there are 4 options as to which stamps to use on the
outer envelope:

1. 83 cent stamp with an old lady on it in black and white

2. 60 cent love with 23 cent george Washington

3. 2 60 cent love stamps

4. 1 60 cent love stamp and 1 37 cent love stamp

We are opting for #4.

what are your thoughts??????
