Hmmm. I am not sure about the 3 month versus the 4 month. To me, it doesn't seem like a month is much difference. I guess it would depend how many blocks I needed to make and what time of year it is. Could you somehow have a group that wants to do 3 months and another group that wants to do 4 month? We still have several that have not been received in this swap and it is a 4 month turnaround time. Hopefully we will get them by the deadline.
