basic question re: focusing rail

hi:
1. i'm going to purchase helicon soft and have one question in regards to shoot technique. what is the recommendation in regards to whether or not one should utilize a focusing rail (such as the really right stuff one). my set up is going to be that of a DSLR with a 70mm macro (ie Olympus E-5 with 35mm macro). i've scanned the various articles on helicon focus and some folks note that you can use a focusing rail while most simply recommend manually rotating the focus dial on the lens. the only reason i'm interested in the focus rail is that one can more easily fine tune the focus and do so in consistent increments. on the otherhand, i would think that using a focus rail would confuse helicon focus because the camera is going to be slightly moving on the rail and thus each photo would be slightly different from each other.
thanks for the help. harry shin
