Another possibility is that all the jumping from one saddle to the next to the next is part of the problem and he's not allowing enough time for his body to adjust to any of them, or to play with small adjustments to saddle position or tilt that might make all the difference. Discomfort from the prior saddle could be lingering and though the next saddle would be fine on its own, sitting on any saddle would bring back the past discomfort.
