you might even want to go smaller, like a 142 to 144 imo. really lookinto the www, it has a smaller tip and tail so you can downsize quite a bit but have a longer effective edge then a normal board. since your so used to your long bullet, this might be your best bet. But a 157 is huge for a guy who is 140. im 170 and i ride a 156 all over. but thats what i think you should really look into man.
