Hope you are getting it tuned.
Usually a bowyer recommends Brace height range.
Since your having another built be sure to ask them what they suggest.
There are so many hybrid type bows it used to be recurves had brace heights from 7 1/2 to 8 1/2 inches.

Heavier arrow

I've always liked the looks of the Prairie Swift.  Sounds like brace was the issue and its normal for most common design recurves to like it at 8" or darn close.

Talked to the bowyer and got the height right, what a difference , wow, went up to a 690 gn arrow and that helped but I think the big thing was the brace height THANKS EVERYONe
