Hello fellow Scholars, I need your help.

I am currently going the Crit+DET route on my novus, as I think that is the best bet. I was also going to use sands to upgrade my sold armor because it has crit, but another fellow SCH said I should go toward a SS/DET build. His reason was because with all the crit from armor+weapon, I wouldn't get much benefit from all that crit. Anyone else have thoughts on this or can provide some insight before I move forward? Thanks.
