Jake decoy hands down. A full-strut decoy not only scares away 2 year olds, but they are a pain to carry.
The exception to full-strut decoys would be if I was solely hunting a dominant gobbler. If I've watched a certain gobbler run off several other gobblers, I'll through some type of strutting decoy out. At this point, I'm not worried about the decoy running off subordinant and satellite gobblers.
