Bars are designed with backsweep so they are ergonomically more comfortable to ride with.
Your hands will naturally be at a slight angle if held out in front of your at a standard bars width.
To make your bars ergonomically comfortable if you have zero backsweep bars,. cut them shorter,.
the closer your hands are together the less angle they naturally create,. thus is you have zero offset bars and they are nice and short you will not experience that much wrist pain.
Short bars require more strength and leverage for some tricks because you are pulling and shifting your strengh at a more centralized point than longer bars,. this creates more pressure on your arms.
so its up to you to decide what to do.
