I used to ride a bullet and rode a friends BTX board...
Basically your going to feel a huge difference in the way the board grips in turns. You will likely feel almost like youve gotta force it to unhook from the mountain to initiate the other direction of your carve. Basically it's going to feel a lot like it wants to mysteriously stick to the mountain.. Other then that your probably not going to see a super dramatic difference.
The magne traction on the board is what's going to make all the difference in the world
