Any chance you could catch a few SMB in your area to put in now. Eyes would be better than nothing. I know Dave Willis has indicated the possibility that YP will get to far ahead of SMB with the resulting problems. The bigger YP and RES will not be the problem it will be their swarm of babies. You will need a predator. A few (10-15) local SMB in the 10-12in range would IMO be worth the risk of introduced problems. Check to see that they are from a location with no occurrence of VHS etc.
