How to Dragoon per Second: A DPS Paradigm

[aleph_null]

Hello,

My dragoon is my only job, and I try to have the best stuff, as everyone. But I don't know how to choose between different gears. For example for feet, I have :
+ Prototype Alexandrian Sollerets : IL 250 / STR 89 / ACCU 72 / VIT 98 / CRIT 51
+ Shire Pathfinder Sollerets : IL 260 / STR 96 / CRIT 76 / VIT 107 / SS 53
+ Diabolic Sabaton of Maiming : IL 260 / STR 96 / ACCU 76 / VIT 107 / DET 51

I know that STR is very important, as CRIT and DET. So how can I make a choice ?
Thanks for advices

There's this thing called "stat weight" which pretty much gives a value for crit/det/sks in terms of str. Check Dervy's site for details: https://dervyxiv.wordpress.com/stat-weights/

Then you can use Ariyala's website (http://ffxiv.ariyala.com/DRG) and click on the BiS solver to show stat weights for every piece.
