Eric, I've never thought about the line tie in those terms. I use to do the two hole method and tried to get away from that one. It's hard enough to drill one hole perfectly centered.
On a body style like the bait posted, I tend to fall toward the straight lip. My mag diver pattern has a 10 degree lip angle but it's a much different body style with a deep belly. Jbass the best thing to do is try both methods and see which works the best.
My mag diver comes back to you from the other side of the boat.
Jbass, keep reading that info posted by Eric. The man flat knows the deep running bait.
