If there is no injury involved, and you can still handle the 15lb; I wouldn't drop down. For me I had to, the pain was terrible several hours after bowling. But I do not think I carry as well with the 14lb equipment, it may be one strike a game; it's hard to say. I know I worked hard on my spare shooting all summer long to offset this, so I wouldn't drop in average. I wish I would have purchased the same equipment, but I throw mainly a 14lb Trauma Recovery and I had a 15lb Charcoal Executioner.
