Carbon filtering with a cartridge with good results - but what about cask entry?

[needmorstuff]

I have carbon filtered by white rum with good results.

I am running 300 litres through 4 plates a mix of 200 litres rum beer 11%  with low wines of 100 litres @ 50% 

Collect around 92% throughout.

heads around 20 litres, hearts around 40 litres, i continue to collect some tails but it's a long day so don't take it all. 

I proof the white down to 50%

repeat the process until I've 200 litres or so

then carbon filter with an amazon filters 10" cart @ 5 micron on a loop for about a couple of hours at 4 litres per minute.

The carbon filtering gives good results, it improves the nose and the taste. It doesn't strip flavour - just improves things.

I plan to put some liquid into ex 1st fill bourbon quarter casks soon @ 60% or so.

Would it be advisable to carbon filter before going into casks? anyone have experience  of that.
