I have the Contour Elite, which is slightly lower power (16 ftlbs). I have had it about a month, and haven't been shooting my heavier rifles since i got it. I plan on selling my heavy rifles and complimenting it with a more powerful, but still light rifle. In general, it is a joy to carry and shoot. Sometimes a pellet will start to back out of the magazine if I didn't get it all the way past the o-ring, then it will jam when trying to cycle to the next shot. It is very accurate and pretty quiet. Mine came with a Hugget moderator that makes it quiet enough for the backyard, but still not the quietest.
Think of this rifle as a p-rod that has been modified with a really nice stock, an accurate after market barrel, and tuned to shoot a little more powerful, all at a price less than the cost of the modified p-rod. My scoped Contour was noticeably lighter than a scoped Mutant shorty (at least a pound lighter).
I can't predict if you will like it, but it is powerful and accurate enough for small game out to 50 yd, is as light as you will get for carrying in the field.
