Before going that route, how big are these two arrays ? Short term can be 64
ref, long term 32, how big in bytes that is ? Was is worth goign with
dynamic
array ? Its not like slices, where we can have 600 or more.
The short term one can still be quite big, it's about 80 bytes per 
element, so 5120 bytes for the 64.

I don't know how often we go that high, I've seen around 10 short term 
ref sets in test videos.
We've never defined a threshold, so its hard to just define which direction to
go. I generally think using dynamic array was logical thing to do though.
