Postmaster vs WBT spades

My Kimber KS3035 comes with the postmaster spades and I'm thinking of reterminating them using the WBT silver spades. I wonder if there a marked improvement with the use of the WBT.

All advice are appreciated. Thanks.

Honestly I'd leave the Kimber spades on there, they are actually very good spades. I don't think you'll hear a darn bit of difference between the two and it will cost you some $ and some time. Just my two pennies worth.
