When looking at bow reviews, a solid back wall seems to be desirable by many. Would I be right in thinking that the Bowtech Assasin and the Diamond Outlaw have a solid backwall and the Mission Riot and Quest line not so solid of a back wall? Is there an advantage to a solid wall vs softer one, or is it just preferance? Reason is I think I have a preferance for a soft wall, and would like to know which bows in a $500-600 bare bow have a smooth draw and soft wall. Thanks.
