Normally I use the AM1-BCC charge and gaff for them.
The answer by Mangesh Damre is also useful.
Have you checked any thermodynamic properties?
What do you think about SwissParam, MolMeccano, GAAMP?

Sometimes people justify the imposition of restrictions on the length of the bonds the fact that in such way simulates a quantum mechanical effect of "freezing" of high-frequency oscillations.
