I think you can pick your poison on the fork since you're going to be taking it easy. If you were going to run fast, difficult terrain or doing a lot of jumping I think you'd want a beefier fork. @Tallbikeman ran Varsity based klunkers in downhill races in Marin county back in the early days of the sport and I'm pretty sure he ran the stock forks with good success. The forged Schwinn Ashtabula forks are pretty strong. The tubing forks are weaker. If you ever come across a 26" Ashtabula forged reinforced BMX fork, I think that's the one Charlie Kelly ran on his klunkers. And he's a big guy who rode really hard.
Nice group of badges. I really like the Schwinn The World badge, very cool.
