All the best Forest with the stock piece, I'm sure it will be fine. I'm using two partials and ready to order a stock piece in the next
weeks as I have a similarish problem - the strange thinning at the back of the head and noticed I'm beginning thin on the dome.

Still got a few tubs of concealer left so will use them sparingly on the balding dome then switch to the topper/piece.

One good thing is that the partial(s) are a good introduction to wearing. So I think it's helped a lot and will be a lot more relaxed
about switching to the full beast

P.S Mr Burns your hair is brilliant, I love how you DIY with it and I'm actually tempted to go the same route once I wear a larger piece
and try cutting it myself.
