Back end slides out

Hey all,
Previously I rode a 163 board and had no problems with control...I just
started riding a new 157 board and am finding that I dont nearly have the
same control...especially on straight riding.
Bindings set up the same..perhaps it has something to do with sidecut.
Any ideas appreciated...

Which make, model, and year are the two boards?

The bindings may be the same width apart and the same angle but it sounds
like your stance may be more centered than it was on your previous board.
Move your stance back a couple of centimeters and see if that helps.
I went from a freeride to a freestyle board and noticed the same thing. The
freestyle board had a centered stance which made me need to set the stance
back a bit to prevent my tail from washing out.
