I've read reviews and seems like the TRS is a great board, with the MTX (magne-traction) tech less noticable compared to other libtech boards (basically like a 7 point serrated edge). Which with the MTX, some people love it, some people hate it. People say it grips a lot on ice, others say it makes you catch more edges and fall over more.
Some people that hate it, love the Vario Power Grip technology with Never Summer, basically varying sidecut radius on the edge for grip curving in the same direction, rather than a wave shape with 7 pts of contact.
Other boards that you may consider for what you are looking for is the Never Summer SL-R, NS Evo-R (softer park board, but people say it still holds up well on groomer and as free-ride, if you get the length for all-mountain riding), Rome Pusher 1985 (rockered Agent out for the 09/10 season), Rome Postermania 1985 (a softer version of the Agent, rockered Graft), K2 Jibpan, K2 Turbo Dreamer, Libtech Dark Star, Burton Hero (I heard burton is also having a whole fleet of rockers next season), Capita Horrorscope.
Most of the boards that I listed would be very well sufficient for doing presses, in fact with the rocker or banana technology buttering and presses are much easier than their traditional camber counterparts (all the boards I listed are reversed camber, thus with banana or rocker technology)
There's probably a lot more good candidates, I just listed a few. Another technology that may be worth looking into is the TBT from Bataleon.
You should probably demo whatever is available in your area, and purchase a board based on what you like, definately try to demo a Libtech with MTX, see if you like it.
