I always think we gain a tolerance to seats, they start as comfy and after a few months or so I don't value them the same anymore. That one looks properly cushy, though.
I know you don't really worry about heat anymore, but how hot do Harleys run in the summer, don't they radiate a lot of heat upwards towards you? On one hand they're big and air-cooled, but on the other they're not very high on specific power.
