Been buying & using wiggle tails for a couple of years now! These painted ones are shit, crap movement & feel like cardboard! And you only get 2 in a pack! The holographic colours have pretty good movement, keep in mind I use mostly Jumbo size for pike flies! The metallic colours like orange & Copper have the best movement out of the lot! The plain colours like green, yellow & white have OK movement, much better than the painted ones but not as good as the holographic ones! The new dragon tails are Awesome! Size M is good for smaller flies, I only have holographic colours! Size XXL is value for money & you get a lot in a pack, but they need some material cut off of the inside curve to move better! Black is made of some swade leather like a shamoi for the car!
