Just feels really strange in my hand, like there is nothing there.
That's exactly what it is suppose to feel like. The wider the grip the more side torque your hand applies to the bow. A thin grip is an accurate grip.
The focus grip is a step in the right direction but why in the world they chose to make it out of "grippy" rubber is beyond me. It's like they have all of these wonderful engineers working there and not a single one of them knows how to make a proper grip.
PSE and elite have the best factory grips out there IMO.
I would personally look past the focus grip and look to Shrewd, Loesch, TorqueLess, Lambeth, etc...
