Most of sperry tools are design released pre-HAL acquisition of dresser.
Sperry is losing all its technological advantages in the market. To make things worse HAL invests very little in the RnD of Sperry (what do you expect from a PUMP company).
Sperry has only its solid team of good people, but now HAL seems to get rid of them before releasing Sperry to the buyers. Hoping for the best for Sperry boys
