Do you know what a pin is suppose to do? The blech 98 would be one of the last sticks I'll ever consider modding, waste of good lead. At 2pts and sw of 330g, to get it to 8 pts I need nearly 22.5 g for 9 pts I need 24.64g and 10 pts 30.24g. All that lead just to re-balance it and nothing to make it more stable. As for the KI system unless your swing is as jerky as an old man with arthritis how can a bunch of tiny bbs make your swing go all wonky? Or were you distracted by the tiny rattle?
