When adjusting your TC you can fine tune it with both fork placement in the TC and how far back you run your rear wheel in the slots.
Dropping the forks in the TC will make the bike steer quicker. It feels just like you have a smaller offset. Typically forks are not dropped more than a few mm.
Moving the rear wheel ahead in the slots will make the bike handle quicker too.
If you bike is pushing in the sand the rear sag might have something to do with it. If the sag is correct then add some compession damping. And take some air out of your tire. If you can't find a balance between pushing in the sand and deflecting off of high speed or slow seed bumps you need to have your forkes restacked or revalved and stacked.
Why would I want to do that??
