I'm coming late to the convo, but the goal is a low-med light no co2 tank right? Seems like these options are putting you way over that goal IMO. I know someone who used the planted+ on their 29 and ended up going with a current sat+ instead because the the planted+ was a little more than they wanted to deal with, light wise. If you plan to go high tech down the line, then a dimmable higher end fixture would not be a bad idea, but if you don't foresee that happening at any point then I don't see the need to spend the extra money on a killer fixture just to dim it down.
A 2 bulb T5ho is more than enough to put you into low-medium lighting as well. Not nearly as efficient as a LED setup, but typically cheaper initial startup cost especially for the lower end models.
*edit* just noticed you said a tall hex 29", not a 29g. I can tell you that on my 120 with a 3 bulb t5ho 27"ish off the substrate, it did OK but nothing spectactular, so a higher intensity fixture may be in order. I don't have the time right now to compare the PAR data for the varying finnex fixtures, but I think I'd likely side with the ray2 if I had to make a choice right now.
