Awesome! Do you think temple flaps would be necessary for this?

No, you'd only need temple flaps if your hairline went lower than this & straighter than this.

You obviously workout, so think of it terms of building up your arms.
The more you build your biceps, the more you need to build your triceps, to keep the overall look balanced.

In this case your 'biceps' depleted (ie your front hairline thinned and receded) and you're building them up to match your triceps (your temple hair), but if you go further, then you need to start building both to keep the balance.

Thanks!

Here's the updated template thus far. What do you think?

Its a little hard to tell from just that angle.

I just added a second picture to that post.

New pic.

To me, from the angles I can see it at, it doesn't look that much different to your first template.

But if you order it with this hairline, you can always modify the actual base by trimming away the lace in the corners of the hairline if it doesn't look right.

I actually cut away a significant amount. The sides are rasied up by at leaast 0.5" and you can see the recession in the hairline in the side by side pic. In the second compare you can see that the hiarline meets the temples at right about the exact same place as in the photoshopped pic.
