What graded cards do i collect specifically?

i was talking with a friend today and he asked me what i like to collect.

so i thought it would make for a good blog and decided to write one up,
here goes:

what i like to collect are graded rookie cards across all sports, with
a focus on modern cards (1970 to today).

when it comes to Hockey rc's...

from 1970 to 1989 i prefer Topps (unless the player wasnt in Topps,
or there is no Topps ('82 & '83), then i will add his OPC).
from 1990 to now, i prefer Upper Deck Base. For the most part, that means Young Guns. I am also considering adding Panini / Donruss "Rated Rookies" to my cannon.

when it comes to Baseball rc's...

1970 to 1979: Topps, Like Slabs in the 7/8/9 range
1980 to 1988: Topps, prefer to have their base rc over a "traded". Like Slabs in a 9
1989 to 1999: Topps base where applicable. Then the other companies, in a 9
2000 to today: Bowman Chrome where applicable, in a 9/10

when it comes to Basketball rc's...

1970 to 1979 Topps, Like Slabs in the 7/8/9 range
1980 to 1989 Topps, Fleer and Hoops Like Slabs in the 7/8/9 range
1990 to 1999 Topps, Fleer and Hoops Like Slabs in the Slabs in a 9
2000 to 2009 Topps, Fleer and Prestige Like Slabs in a 9/10
2010 going forward: Donruss Rated Rookies in a 9/10

when it comes to Football rc's...

1970 to 1979 Topps. Like Slabs in the 7/8/9 range
1980 to 1990 Topps, Score and Pro Set. Like Slabs in a 9
1991 to 2000 Topps, Score and Ultra. Like Slabs in a 9
2001 to today: Topps and Score. Like Slabs in a 9/10

are these steadfast? not always, because sometimes a lower grade slab is too hard to pass up when really low priced.

There you have it, that's my current focus in a nutshell

Thanks for the read,
Eric
