I see where you are going with these, following our sister company's logo. I think they are too similar to it though. I would like to see this logo have a bit more of it's own personality. I like the minimalist direction and your choice of blue is spot on. I really like how you have incorporated the "+" in Entry #5, we have a series of "plus" products in our line and it implies you are gaining something but it reads a little funny. It looks like it says G+IT, is there a way to have the plus but still make it read as GHT?
