For the holes. Andrew G's dive xtras developed a spool that has two nice features. Larger holes so the problem you guys were describing becomes a non-issue. At the end of the line (near the bag), he has a swivel like mechanism preventing the line from twisting on itself. I would definately look into it, great stuff. It is not on the website, email and ask for it:
