The Dif-Fly quickly stole the spot light from the Duncan Cold Fusion and the Tom Kuhn Silver Bullet 2 as the best Modified-shaped aluminum ball bearing yo-yo. Around the same time though, YoYoJam's composite-material yo-yos were gaining popularity and naturally, Frank's designs changed to accommodate popular demand.
- Dif-e-Yo Daizzy-Fly - Dif-e-Yo's second collector model and the basis for the Dif-Fly.
- Dif-e-Yo Spike-Fly - Made-to-order multi-style variation with YoYoJam spin top tips on the sides.
- Dif-e-Yo Zzzip-Fly - Undersized variant of the Dif-Fly.
