I'll stick with blood. One point to consider- one of my hunting buddies lubricates his, and complains that the blood from the hit doesn't stick to his arrows, making it harder to tell the nature of the hit by the blood evidence.
I use fat arrows without lubricant, and none of the deer have noticed. My Superceders were made up to 25/64 in the untapered center section, but passthroughs are the norm when the arrow is properly tuned and the broadhead is truly sharp. When Tom Jeffrey (Owen's son) was using them, he killed more than a dozen deer and hogs from the first dozen Dan sent him, and he still had 6 left when I talked to him later. He said he only lost an arrow if it stayed in the animal and it got rolled on. The majority were passthroughs. I never had a single complaint on penetration from a few thousand customers. Good enough for me!
