i have todd helton and James loney for my 1st base and utility with Matt Kemp on my bench

am i best to start Helton the days he is at home, and play Kemp and Loney the days the Rockies are on the road?

if you think about it, the disparity of Helton at home vs. the road is huge.

or should I just play Helton every day?

I also have Holliday but I play him all games.
