You sure? I have A LOT of gens and reps, and must say its hard to get rid of my reps altogether. I mostly use them for experimentation or gen stand-ins or for creating fantasy versions of the gen or as gap fillers in my gen collection to keep things interesting.

Gens are great if you can afford to acquire them but they can get boring in the long term as you would have nothing to improve or work on unlike reps.
