Skeg length / shape question.

[Mr. Demeanor]

I am thinking about adding to my skeg.
For those not familiar I run a transom water pickup allowing me to run extremely high engine heights. My boat / motor love the height. It porpoises less before packing air, launches flatter, and is simply faster.
I have about 3/4 of the top of the skeg out of the water at speed.

The downside is excessive crabbing and in some conditions like crossing a wake Im running alongside when one sponson goes up and over the wake the stern lifts and she wants to walk out to the right.

I have two ways to do this.
#1. Add to the length of the skeg. I could easily add an inch to the bottom of the skeg but this would increase the leverage/stress on the top of the skeg where cracks have been an issue for me.

#2. Add to the front of the skeg. I dont see where this would add as much stress to the upper rear where skegs tend to crack. In fact, I think it might actually help by moving some of the stress forward to the stronger thicker area of attachment to the bullet.

In my mind I "think" adding to the length would create more drag than adding to the front.
I also "think" that adding to the length would help handling better though.

Thoughts?
