    Alberta, -are you absolutely sure the 12mm mains aren't 2-pass 55lb/ft then 90 degrees?

    I seem to have some conflicting information, -just want to be sure.

    BTW, nice work man!

    NOTE: Alberta Redneck edited/proofread everything and made the changes required. The information that you now see is correct. --JiFaire

    If a Mod could delete post 3,4,5, & 6, that would be great. I fixed them up, made all the editing the same, and combined what was missed. Thx

    -- Done. The incorrect information is removed. -JiFaire
