Both feel nice, but in my opinion you will prefer the feel of the PMR.
My reason: Its lighter than a DM5 and it has the sexy UL frame on it, i held one of these on thursday and let me tell you. Man does it feel nice. Not only does it look the dogZ but it feels so good and natural, it just sinks into your hand. Its great.
But its your choice, i dont want you to feel we are presurring you into a choice.
He could buy a DM5 and then get a UL frame like you said, but then he can get a UL frame included for a fraction of what they cost new included with the PMR.
