X2 I agree. I also think a single top hook is a much higher hookup percentage, since the fish has swallowed the bait, and that big hook at the end of heavier line, on a heavier rod, sticks them really well. A good sharp hook is key. A hook that big that's dull won't get into the fish's mouth.
I'll go one step farther, and say that I think using a big, solid, embeded hook, instead of a through line and top set treble, gives me a much more solid hookset, too.
I used to throw Optima through line swimbaits a lot, with a #1 belly treble, but I found that the multiple points seemed to spread the force of the hookset, and a lot of fish came up and spit, or had the hook fall out in the net.
That doesn't happen with a sharp 6/0 tophook, and I don't worry about getting snagged when I fish the bait slow and deep.
I use the same swimbait mold as Longhorn, the Lurecraft 5" 5/894. It only uses 37 grams of plastic, and it's big enough to attract good fish, but small enough for them to engulf.
If a bait gets torn up, I cut out the hook, remelt the bait, and repour.
