[IQUG] [iqug] Simple question

Here's a simple one.
Is it worth putting an HG join index on a 1 mb table with 6 rows which is being used to join to a 172 million row 68 gb table?
Not just joining on the HG col but I have a where "col from this small table" = 'value'
I'm going to guess it wouldn't hurt.
