SU Needle Recommendation

71TR6

I just purchased a pair of HS6 carbs off EBAY for my 71 TR6 to replace the problematic ZS carbs. I'm currently waiting for them to arrive but have a question for the forum in the meantime. I know there are a broad range of needles available for these carbs. I'd like your opinions on what needle size works best for a stock 71 TR6 engine.

Thanks!
