Have had great success with both types, as long as the rest of the trailer is setup correctly. My current trailer is a full roller and I have to be careful as the boat rolls off very easy ! I am going to tighten up a couple rollers as they are to free currently. Trailer setup is "everything" no matter what type you have, take the time to get adjustments made so your boat is always centered and comes off and goes on easy. If your boat does not do these things...fix your trailer...so it does. No excuse for fighting loading and unloading unless you have a poor ramp.
