you make a valid point,and i definitely wouldn't argue with success.
and you are correct,being in a field that the birds want to be in ,is a major factor to say the least.
but with that aside, i just have to wonder if birds are flaring due to minor detail in your decoys profile, if it may be more of an overall visibility issue,some days they can just see too well.
SCM, i also like the heads in the spread,we use quite a few (Silisocks,, spelling ?)
just for that reason. there overall profile is nothing like your average sock/rag,
we have been combining decoys for years with without any apparent problems. but iv never claimed to be good, just lucky
