Looks like a fun project. This is the base set parallels I am looking for. Only own 5 (Ovechkin, Duchene, Tavares xx/50 and Luongo, Malkin xxx/150). Buying common dual at $3 if interested (would have to in lots of five or more).

10-11 Artifacts treadelist includes; 103, 113, 116, 136, 159, 178, 193, 199, RED 241.
Tundra Tandems Eric and Jordan Staal white/white (TT2-Staal 056/125)
Emerald 146 (05/50)
Treasured Swatches Tavares Emerald black over black (TS-TA 04/15) and Gionta red/white over blue (TS-BG 4/5)

Thanks, Russ
