Subject: [AMBER] distance restraint and SHAKE

I am running MD simulations of a patch of helices. I would like to keep these helices "helical" during some umbrella sampling calculations. I am currently using standard NMR restraints to hold the O-H atoms around 2Å. Although now that I think about this, it probably is not a good idea to use the SHAKE algorithm concurrently.
Anyone have any insight? SHAKE or no SHAKE? Better method of keeping helicity?
