If you are shooting over deaks all you need is 4s or 2s
As far as chokes steel is one size different than lead. A mod lead choke is a full choke in steel . Hope that helps. I think that the imp mod choke over deaks is to tight in steel. I would use imp cyl over the deaks.Just my 2 penneys worth. Have Fun
