Get the group 30s for both and be done with it. They are the real deal. The 27s are good but if you can swing it get the 30s. By the way there warranty is second to none. They covered one for me that was 6 months out of warranty. It was a Group 24. Service like BCB.Last edited by Bama96 on June 18th, 2010, 11:03 pm, edited 1 time in total.
