After a lot of practice and a little research I found out that my draw length is actually 26.5" , so using 2018s I was way overspined. With my Crusader being 52# @28" I was planning on going to 2016s at 28" with either 125gr or 145gr heads.
With a 125gr head,a 1916 or 2016 would work well.With a 145gr head,a 2016 or a 2018(a heavier point will weaken the spine of the 2018' s you already have).
