For hunting over water, I generally dont really call as they are feet down, and comin hot. They seem to get plenty close without making much noise... But when we hunt ground blinds in hay fields... The geese seem to really like the super cluck, or a constant, quick series of moans. And as with any calling. A clean, simple moan, or feed call is way better than trying to hail birds when it sounds like.. An elk in a bear trap! Very true!
But the most important aspect to calling fowl... youve already observed. Some are real social butterflys, and some are as quiet as can be. Just like people, it prolly depends on their current mood, as to which type of call/s and spread they find most attractive.
But to answer your question finally... It all depends on how you learned, and what you feel confident in. Thats why some guys call til the birds are down, and some quit as soon as birds look comitted. Its definetly something I go over with guys that have never hunted with me before. It helps to avoid someone lookin like an A hole... Usually!
