Thanks for the additional variations. My favorites of these are #177 and #174. The two-color scheme in #177 is close contender to overall favorite
#35. The extension of the 'h' so that the 'R' loop is painted over it is very effective about drawing attention to the 'h'. Still wonder if lighten the dark gray of the 'h' might work better in the design? I like the way you've broadened the design in #174, which serves to de-emphasize the 'R' so that the 'R' and 'h' are similar in emphasis. Some of my associates start to lose the 'R' altogether, but I personally very much enjoy this modulating design.
#167 is a very strong graphic design. It could certainly work for me, but I prefer your softer 'artistic' designs.
The circle in #173 does not work for me in this design.
Thanks again for lovely refinements! Best, Roger
