I own the HOLE,here my opinion about the hole.
the advantages of the hole:
-No puncher needed.
the disadvantage
-sometimes the movement will stuck,need practice much to make it smooth.
-complicating to repair the gimmick.
Anyway if you not care to carry a puncher,i HIGHLY recommend BEyond Holely by Will Tsai,using borrowed bill very powerful :) and the pricing not so expensive.
