If i was going off your list alone I Personally would get the Lyman or the Murray.
what about the '08 murray? why '07 specifically?
without reguards to your list i would suggest trying a slingshot board. Best soft landings by far. super fun to ride and great pop when you edge into the wake right.
I rode the 07 Murray and it slow to me. I am waiting to ride the 08 to check it out. I am an intermediate rider also and maybe its my riding style, it just didn't fit me well.
The 07 Murray had to much rocker 3.10 and it made the board really slow. The 08 is great, fast, big pop and lands really nice, the rocker on the 08 is 2.80. The B-Side is another great board from Hype, I would check that out as well.
