Quick question, I compared my auto single logo batt with my brother in law's auto full logo batt and I noticed that his have smaller air holes. I tried his and I found that I like the draw on his batts better. Is this also the case with the manual batts? (single logo having bigger air holes/full logo having smaller air holes) I'm planning on getting a manual XL batt with the smaller air holes. Can anyone enlighten a newb on this?
