+1. The smaller chainring and/or larger cog will lower your gear, which will make it easier to skid/drift/wheelie.
Unfortunately, since it's a lower gear, your bike will go slower for the same level of crank RPMs, and you're more likely to get spun out going downhill, so you need to find a happy medium that works for you.
