I shoot couple times a week with a older gentleman. He is very knowledgable and analyzes everything. He watches me shoot and what he keeps telling me is that i use an open bridge on shots i shouldnt that is why my position play is suffering. He told me that i should not use open bridge when using top and bottom especially top. He says that the shaft deflects off the cueball to soon and that why im not getting the action i need and it has got me into the habit of shooting to hard to get position. I can see his point but I never think of what type of bridge im using when i shoot. i just go with what is comfortable at the time. What is your opinion on this?
