The issues you mentioned about birds nests are a result of two things. "Spin up": the speed of your line leaving the spoon based on velocity you which launch your gear and "over run": the speed of your spool when your gear contacts the water..
Your thumb is the definitive braking component to prevent over run. Before you make your first cast after rigging or re baiting you should take a moment to ensure your mechanical spool brake is adjusted to allow your gear to slowly drop towards the ground while free spooled. That will help mitigate the effects of spin up. The moment your gear contacts the water, stop the spool rotation with your thumb. Often you won't need to engage the gears, rather you can continue to drift with your thumb on the spool and simply release pressure to ad that little extra something - something to the swing at the end of your drift.
It's also a good way to release any accidental over run you might not have been able to stop. It's never a good idea to reeling line on top of loose loops on the spool. A wrap is bound to happen at some time and that stops casts like hitting a brick wall.
you may be letting it go too late, but with a bait caster weight helps a lot
