I checked mine once in January of 2013 and then went with your philosophy of what will be, will be. Only a few had rotted by the time I got to plant them so it wasn't any major loss.
I'm impressed by anyone who can locate the eyes well enough to do the Saran wrap method. I keep the whole clump and end up digging huge holes each June. I've seen photos of the eyes, read descriptions that they look like potato eyes, and yet can't see them.
None of the work involved keeps me from looking for more. It's an occupational hazard!
