Fusilai build question

[tedbearr]

I made the fusilai for my saryn spore build with concealed explosives since it seems like it is the best throwing secondary for the job. 

I was playing around and found out I could make my own blast with the other two dual stat mods and go to to 100% status. I was thinking, what’s better?

A. Blast from concealed explosives with a high status chance and one extra mod slot for something or

B. 100% status with better(?) blast damage at the cost of using up all my slots?

So if I use A what mod should I put in the empty slot?

My current build is hornet strike, barrel diffusion, leathal torrent, all four dual stat elemental mods to get corrosive and blast, and finally pistol gambit. This brings crit up to 50% and status to 100%. (Option B)
