Don’t really have anything that is 55 grams. The Aldila NV Iron in is 58 g in the and 61 grams in the R and is a really good seller ($27.99). Both have a little less torque and are Mid trajectory shafts vs the Apollo. The Recoil ESX in the 460 A (59g) and R (64g) have a little more similar torque, closer to what Apollo lists, and is considered a High trajectory shaft like the Apollo. Price is $39.99 for the Recoil ESX 460’s.
