Hydramat.. Is it worth the $
 

I have the Holley tank kit (Tanks Inc) 19-401 which has the 400 lph fuel pump and says "Internal tank baffling includes a large 4.3 liter internal fuel tray to prevent fuel pump starvation"
I asked Holley about a Hydramat for this tank and they said the 16-124 ($158.94) 3" X 8" HYDRAMAT®, RECTANGLE CENTER OUTLET would be a good mat for this tank. Would it be worth adding the Hydramat?
Opinions? Facts? testimonials?
Thanks

Curious too, following
