My best friend was the one who got me into hockey cards, and I had a bunch that he gave me from the 1972-73 season, and I collected up until 1979 or so. Sadly, those cards are long gone.
But with my return to baseball collecting this year, I decided to start a PC of one of the most exciting young players on my team, the Flyers: Claude Giroux. So last week, I found a seller on eBay auctioning a 5-card lot of Giroux base cards, and I took the plunge:

Giroux's got an extensive checklist (especially for a young player), so I think using him as my hockey PC will keep me busy there. Plenty of GU's and autos to go along with his base cards.
Don't hesitate to steer me in the right direction - I'll be looking mainly at Upper Deck, SP, and Panini. I don't like the O-Pee-Chee cards, and I won't bother with the likes of Fleer.
