Clearer Plastic as said by Dave is usualy more overstable than Pearly Plastic..
The pearlescent material is a weight agent just for eveyrone's information.
A clear 175 teebird will probably be more stable than a pearlescent one although I"m sure I wouldn't notice the difference.
I disagree. Ive always looked for the most clear versions as they will flex earlier. So that makes them less stable than the Pearls. It has been the way with Pro Line Beasts, Vikings, Orcs, Teebirds and even Champion Gators. IMO.
