CHARMM Development Project Forums User Discussion & Questions Parameter Set Discussion Piperidine Parameters

So, am I right, that it would be better to create topology for cyclohexanone based on all35_ethers cyclohexane topology, but to use parameters from CGenFF? Should I than use Atom Name CG321 (aliphatic C for CH2) for the chain carbons, CG205 (carbonyl C: ketones) for carbonyl carbon and OG2D3 (carbonyl O: ketones) for the oxygen?
Or is it better to use parameters for the most molecule from all35_ethers parameter set and to take only carbonyl parameters from CGenFF?

Thanks in advance.
