# 75 and #76 are interesting and creative, though not the look we want. The colors are right on and we like the leaning letters in # 76. Perhaps a few variations might do the trick. Please pay attention to my comments about our # 3 ranked logo, which was banned for some reason. It was one of our favorites, if not the favorite.
As for the large R, it is a nice R, though could be thicker, shorter and more stretched out. We understood what you were trying with the T, but are afraid our clients will not get it and it just did not hit the mark.
# 195 is impressive, but the R and T are not quite there.
# 203 and # 204 the COLORS ARE PERFECT! I love the silver / gray background on the mark, and love the T, but cannot tell what the R is. You are getting close I know it!
