Yes, I'm beating the poor dead horse again. I have searched extensively on TW and still have some questions.. Never done this before either. So yes, I have Bab Pure Storm GT 2011 which is said to be 1 pt head light. What I am trying to do is to make this 4~7 HL and see how much HL i want it to be. First, before customizing, I'd thought I would use TW customizing tool and see exactly how much weight i need to put on the handle to make it around 5 HL (at here http://twu.tennis-warehouse.com/learning_center/customizationReverse.php). But when I entered Pure storm's specification and it says 5 pt HL to begin with, which is not correct at all. So I'm disregarding that tool and just experimenting taking couple swings each time and see how i like it. I wonder why it is like this though. Before I take off the replacement grip I have on and put lead tape & leather grip on, I want to know how much weight i want to add. So I'm using coins (Dimes) in side the trap door to see roughly how much weight i want to put on. I'm putting two dimes wrapped together on each hole (inside the trapdoor) directly against the wall that separate the two holes. I heard that if they are directly against a part of racquet, they might cause harmful vibration for the racquet, is it true? Then when i find the ideal weight do I need to take off the buttcap in addition to the replacement grip? When I put the lead tape directly on the pallet, where exactly do I do it? It'd be really helpful if there is a picture, but i haven't found one. Without taking the buttcap off, should i put it on the pallet straightly along bevels? I would greatly appreciate any help. Thank you very much!
