I'm looking for both of these balls in 15, new or nicely-used.  Pins need to be at least 3".  I would strongly prefer a trade for what I have listed below, but all offers will be considered.  

What I have-

16# Amulet Glow.  Amazing condition, looks almost brand new.  1 drill.
15# Blade Pearl.  Excellent condition. 1 drill.  
15# DC Tour.  Ok condition, has been resurfaced a lot and part of the label is missing.
15# Blue Sparkle Gryphon.  Good condition, small crack on the bridge.  1 drill but ball had thumb slug to move thumb forward, and also finger slugs.  
15# Slate Blue Gargoyle.  Excellent condition.  
15# Uranium Buzzsaw.  Very good condition, with a tiny crack in one of the fingers.  Ball had this crack when I drilled it, and it has not changed.  1 drill.  
16# Omega Lion.  Very good condition.  1 drill.

None of these balls have grips, but all have either a vinyl or urethane thumb slug.  Some also have a vent hole drilled for the thumb.  Pics are available for all balls, and I will also go into more details about the condition, and possibly spans, although they are all different and I have no exact way to measure them.  Thanks for your time.
