Then what does perry reflex do

As bradsmith2010 says, it is a large topic. Essentially, it preloads the belly into tension so that it does not experience the full strain from unbraced to full draw. The method of preloading the belly by gluing in the reflex also gets some work/energy storage out of the core material instead of having it only concentrated on the belly and back surfaces.

I knew it allowed more of the core to do work but I thought that had to do with the neutral plane

bottom line for me is ,, the bow will hold reflex with less mass weight overall,, so it shoots a bit harder for its draw weight,,

This is in favour of Perry reflex?

Perry reflex is far and away easier to implement. All it entails is gluing two pieces of wood together while holding the bow pulled forward into a reflexed shape, which can be as simple as clamping the handle to your bench and putting blocks under the limb tips.

Yes that's what I was asking, ease of construction.
