Im currently using one with 05fx and 80fx.
It replaced an Innerforce Layer ALC, one of the first series.
Crest Ar+ is a very nice blade with a lot of control and enough speed. It's produced by Soulspin in Germany.
It simplifies the short game alot making most of the shots easier, but the topspin is less satisfying.
It's harder, stiffer and slower than Innerforce ALC and the throw is lower. The handle is super confy.
Loving it! Well done Soulspin!!
If u play 3rd ball attack and topspin everything, get a flexier blade tho.
