The lighter you go the comfort goes down... that is the rub with UL! Are you willing to sleep in a three hour downpour on the ground? The pad is there to add a little comfort, I cannot wrap my mind around a 1 pound pad. 8-12 ounces should be enough for a self inflating.... just a couple ounces for a thermarest closed cell.. There are lots of choices. The pad you have already chosen is the best choice. Try to use it more and it will grow on you.
Oh and that part about pad envy.... very cool!
