I know there are a lot of threads on grip preference (interlock, overlap, 10 finger, etc.), but I was watching this video last night and the instructor suggests that an interlock grip leads to "problems". He doesn't really expand on what those problems might be, and advocates for overlap or 10 finger. Just curious what you guys more expertise than me think about this, and whether interlock is problematic.
For me, I've always used an interlock grip because it feels more secure, and I feel like I can use less grip pressure if I do. But I'm having problems with driver contact, pulls, and slices right now, so I'm open to trying something new if my grip might be part of the problem. What kinds of problems could an interlock grip cause?
