Just tried the RF-3 today and must say it is a terribly overpriced product which does not deserve $25 per tube!!!
We were playing a friendly game where say 40-45% of the shots were smashes - required atleast 4 to complete a set???? We played a few sets ...
Only pro is it does not slow down as quickly as the Sintec shuttles.
