If you had to always use the same deck for the rest of your life, what would it be?
Keep in mind the design, handling AND price of the deck in question. You'd have to buy a lot to last a whole life.
If I could afford it, I would have to go with Artifice. A slightly less expensive option would be the blue Crown deck, and if money was a bigger issue, my choice would go to blue Tally-Ho fan-backs.
The reason for my first two options is simple: both have my favorite combination of stock and finish to date.
