B&W C5 vs Grado GR10

I wanted to get the opinion of the people of Head-Fi on these two IEMs.

I generally listen to Grado SR125s and 225is whenever I can.

For reference of my tastes on the matter with non IEMs:

I have auditioned the P5s and for their price I wasn't impressed.

I opted to add another 100 and get the Grado SR225i.

I had a set of C5s previously (until I lost them :S ), and they were good... but only worth it if they were about half price (~$100-$120, not $179-200) IMHO.

I generally find B&W to be expensive for their quality but ok, and I need to go through a few before I find a pair that sounds right.

I also had a pair of Apple In-Ears, and they were crap IMHO, worth MAX $35-45 not the $89 that they sell for.

So you can see how my tastes run towards Grado, and their tonality, in these matters.

That being said, I have heard that Grados lower-end stuff is mass manufactured crap, and that I would probably get better quality out of something like the B&W C5s.

For an IEM, considering my tastes, would you say Grado GR10s or to replace the missing set of B&W C5, or to stick with a new pair of C5s

Anywhoo, thoughts, Ideas, Suggestions?

TL;DR: I like Grados sound, but worry that the low end stuff isn't worth the money, I already tried B&W stuff, and know that, for me, they are about double in price what I would consider fair for their sound quality.

Aaaand, Just noticed the price difference between the C5s and the GR10s. But willing to do it if they won't be a let down like the C5s were.
