In regards to the comb - there is a different interface than anything else i've used and I dont love it.
Comb height to bore is one factor but comb height to butt pad is another. If you mount the butt pad to the same part of your body as you would a more traditional stock to get the benefit of resistance to recoil being closer to bore height for less muzzle rise, that in turn means the comb is LOWER in relation to where the butt pad contacts your body than a straight or positive sloped comb. I prefer a more upright head position and not bending my neck to get my head down for a cheek weld. What ends up happening for me with preferred high rings is I just end up with more of a jaw weld which is fine. The feeling of the stock heal rising higher up the cheek/jaw as it goes back is kind of odd and I dont prefer it but it is not a negative functionally.
The grip, parallel fore-end/toe, and the shape/width of the fore-end to balance carrying comfort and stability on a rest is pure money for me. Absolutely nailed it IMO.
If I could make one tweak to the shape, it would just be a more moderate slope to the negative comb which would result with higher comb height. If it really mattered to me I could easily modify my rokstoks to incorporate that modification with shaved foam, thermo beads, or kydex but its not that big of a gripe.
I have 3 of them and bought them one at a time so obviously i like them.
