Please see my recent "Brief Update" on the main page. It applies to most of your logo designs.
I really appreciate you creating so many different logos! Great work!
One general comment for you, is that the text over-emphasizes the wrong word. Please emphasize 'wealth', not 'engineered'.
#28 is cool, but I'm not sure it reflects the 'wealth' aspect of the business.
#41 is an improvement on #15. I like how you removed the gear. It looks cool, and it integrates the E and W together in the logo, but it still doesn't have much of a 'wealth' feeling to it.
#42, similar comments as to #41.
#46, similar comments again. But, this one seems even more emphasized on the E, and the W is harder to see... Orange is ok, but gold and/or sliver might be better.
