But I have seen a Tru-Glo SSX.670 on a cool 45 degree day out perform my Star Dot. But in 60 to 70 degree weather I doubt that it would. But in all fairness I didn't keep the Tru-Glo long enough to compare it to the Star Dot in this temp ranges which is about avg temp during our spring season in MO. I'll just say my best highest count patterns that have been repeatable have come with my Star Dot choke in decent temp.
