There is no universal trim advice. Every make of boat is a bit different than another, so if the boat plan calls for more metal up front, or to the back, that manufacturer differs from anther.

There isn't anything here that you haven't already found. You know the "slick spot". If someone writes back and says that the stern should be X inches out of the water, and you do it and the boat feels like glue.....well, 'nuff said. It sounds like you know your boat. Stick with it.

I'll mention one thing, tho, my boat is 20 years old ( tho sporting a very nice paint job! ), and I store it propped up with the bow in the air. Occasionally, it fills up with water because it slipped off the wood prop and makes a seal with the ground. The wood under the floorboard gets super-saturated, adding a huge amount of extra weight, right in the stern. Unless I found a couple of monsterously manly types to put in the front, I'd never get it trimmed.

Moral of this story: Don't let your drift boat sit with water in it.
