From a 2012 article found on fortheloveofhockey.com:

Kris Letang has a hard, heavy shot, the kind you would expect from an NHL defenseman with offensive flair.

The kind that would make any goaltender stand up and take notice — if the shot was consistently on target.

“Hitting the net is something he’s been urged to work on,” Penguins coach Dan Bylsma said of Letang.

Letang’s aim eluded him, and his goal total dipped from 10 in 2008-09 to three last season. So — much like teammate Sidney Crosby did the summer before — Letang spent a lot of the past offseason working on his shot.

Also like Crosby, Letang made an equipment change. Crosby switched from a two-piece stick with a wooden blade to a one-piece composite stick. He then scored a career-best 51 goals for a share of the league lead for 2009-10.

Letang, hoping for more velocity and accuracy, is using a bigger curve in his blade.

“I tried it, and I liked it, so we’ll see,” said Letang, who spent hours getting used to the new stick and working on his accuracy by shooting off-ice.
