Use mine in commercial forestry and get on fine. Admittedly it does take a bit of practice and real time use to get the hang of it..Can understand the principle of it but depends on what sort of stalking you do I suppose , woodland stalking you wouldn't get a chance to get the rifle out of the vorn by the time the deer had run off ! ( well I wouldn't! )
I recently thought I would try going back "old school" but found it much more of a faff keeping the rifle straight on my shoulder.
