I'm leaning towards that too.
We never really had a chance to use the 75th set though, we scrapped them after one game because we were embarrassed by the Giants on the field with them...plus, they use the same gold pants we've been using with our primary set.
I really hope the team makes a big effort instead of taking the lazy option (gold 75th set).
The 70th spear set was not a throwback, it was a modern redisgn of the original, so a true throwback to the '65-'69 set would be great.
If I were in charge, I'd bring back the feather helmets! We've used every other "old" helmet in tributes. The feather is still a unique helmet like nothing else used in the history of the league, plus it still looks cool.

a true throwback would look like:
