    I burn a very little bit of oil just due to the heavy load but it's the same wakeboarding vs. surfing. I'm not too concerned with the effect of the...

    They should fit perfect. It has the same overall dimensions (50x24x24) as the 1100#. The volume difference is just due to the circular cross-section.

    And by "needed" he means "the absolute max that will fit"! I think that you'll see a difference between your 800# sacks and 1100# but I don't...

    Ah, now that makes sense but the advantage would be cable size by sharing one shield, but it wouldn't improve noise immunity.

    But with a total investment <$100, I don't think I'd care even if it only lasted a few years. It would still be 1/10th the cost of seadeck

    Coax also prevents EMI. It's just a difference of how the signal is driven.

    We just pulled the carpet out of the lockers. It just pulled right up. We did use a scrapper to get the little stuck on bits but it was pretty easy.

    That's true if the drivers/receivers are differential. If they are single ended (which the ZLD is) then a coax RCA is the right cable.
