If that is the boxwave case I tried, it did not seem that thin, and was the TPU type, soft and foldable. mine seemed kinda loose on the sides cause it is not hard plastic.
 
I received my $3.99 case from Ebay (link here) and as far as I can tell it's exactly the same as the Spigen/Veil. It fits really well and is quite good for the price really.

The only issue with these is that they don't improve the grip on the phone much. I am beginning to think the answer for me will be some sort of Slickwraps skin and I understand they will soon have a clear matte skin there.

I've also ordered a Shumuri but their shipping is slow, and if it is the same material as the Ebay case it may not be what I need anyways.
 
For grip, nothing I've tried is even close to the Bear Motion's Sand series.
Best minimal cover I've had and grippy texture, I guess that's why they called it Sand.
