well if you want to through a HPS bulb into a MH discussion I am not familier with the iwasaki blue bulbs, a side from they were aperantly an ugly blue when they were released, then nothing. so no word of a lie, I have not seen anything on them untill you just mentioned them so how good can they be..

I had the USHIO 175 watt 10K's and while they were not bad I have seen many 150 watt HQI bulbs that would blow it out of the water, it was only marginaly brighter than T5's so how good can that be seriously though, I would put 175's inbetween the PC/VHO/T5 and 150 and up HQI. now there is one factor that might mislead some with the 175 as it is a mogal bulb it has better coverage than a DE bulb so it makes the tank apear brighter, but the intensity is below a 150 HQI.

Now what are ou going to keep, the only differance I noticed is my digitata went from a slow grower under the 175 to crazy fast growth with the 250 SE on HQI ballasts. but if you have a 175 another problem is selection, a 150 HQI has far more bulb choices.
