If you've already used Gaughan, look at Racing Reference. Find the guys with the fewest DNFs. Pick the one with the most points that you're not likely to use elsewhere.
Suarez was my second choice after Poole. If he can avoid the big wrecks he could get a decent finish.I was trying to pick anything but Rick Ware junk. I actually saw Kligerman get to the front in at least one restrictor plate race in the Gaunt Brothers #96 last year. Saving Gaughan for a little later.
