Running a longer ester close to a show ?

what do you guys believe in running a longer ester (like sust, cyp or enth) during the final month before a show? I know back when I was a kid, my trainer always had me switch out to a shorter ester like prop to hold less water. But now with better anti e's (back then there was only novadex and proviron but it was HG) there seems no need to run a shorter ester, or switch out.

I still believe in just running shorter esthers closer to shows, then again i believe in running them soley as im not a fan of long esters mainly because i like to be able to have it out of me fairly fast if any bad gyno symptoms start occuring

I'd definitely switch to a shorter ester just to be safe. I mean yes there's plenty of anti's out there to combat anything, but you're less likely to have any problems with shorter esters and after all the dieting, you don't want something stupid to happen
