Opinions please?

My pursuit of autographed mini-helmets from the top 25 all time NFL rushers has slowed as I continue to hunt for the last few pieces I need.
In the interim, I decided it would be a nice compliment to the helmet collection to pick up a raw high(er) grade Topps base brand rookie card to go along with each of the helmets. This was not originally intended so much as building a rookie card parallel set to the helmets as it was motivated by the thinking it would be interesting to see different Topps designs through the years as the list spans from 1958 right up to 2001.
However, as I got further into the project I came to realize that there are no Topps rookie cards for a few players. For example, the Topps base brand did not include a rookie card for Tiki Barber in 1997. So what do you think, should I stick with the rookie theme and pick up another brand rookie card, or should I hold true to the original spirit of things and use the first Topps base brand the player showed up on? I keep going back and forth between the two, so what would YOU do?

Raw: Tony Gonzalez (low #'d cards, and especially 1/1's) and Steve Young.

How far along are ya ?
And which ones do ya still need ?
That sounds like a collection I would like to have too.
If you would consider changing it, I would do the player's most in demand regular issue RC, which would add value while also sticking with a rookie card theme. You'll still be able to see the Topps cards through the years up to about 1991 when regular issue Topps football became fairly insignificant.
