I’m hearin’ ya, @Hydro-420 !
Earlier I said I may add 1 more tube but then as I was working on the frame last night I started remembering how I used those 3 T5 fixtures before. Like this…
But, looking at it just now when I was squaring things up to finalize the 3 locations for corresponding 1/2 laps, It’s looking like I should probably add 4 more tubes.
IF I proceed now with the parts I have now I’ll be hemmed in to a 3 tube fixture with the possibility of modifying it to 5 at most.
The struggle is real! 
I’m going to let this pondering wade around a bit longer in my Thought Process Machine and see what it comes up with!
