Kamui is the best..
Kamui back ss is springy(almost like its rubber), also as stated prior,it will shroom @ 1st,but after its trimmed once ,it wont do it again..
The kamui black soft is like a medium style tip ,similar hit to kamui brown med,moori med, talismen brown med, difference is kamui black soft wont shroom ,and holds chalk well ,when tips scuffed ..
If kamui black soft glazes over ,it will miscue sometimes,even when chalked, but one tip scuff goes a long way with kamui black tips...
If you have a very, very, stiff shaft, Id recommend the kamui black ss, but if it's only as stiff as ,lets say a 314-2, Id say kamui black soft is the better choice.. Jmho.. Good Luck..
