if you rip out mods from BH pieces and stick them in rakata your gear is significantly better, just requires you knowing what mods/enhancements you need.
This is what I did with most of my gear, although I went back and replaced my rakata with tionese since it looked better with my pink bounty hunter chest. You can keep your set bonuses this way while using your black hole coms that you get through the FP dailies and weeklies to upgrade the modifications. I actually geared out my alt in 61 level mods by doing dailies. There are a lot of different ways to gear up without necessarily doing HM denova. I used the boots for Mercs since those had power/surge stats and were one of the cheaper pieces. Anyway, good luck gearing up!
