Yeah, I did mean 10mm. Apparently my brain is still resisting metric.
The plastic extension on the 101s gives the tail a little more length and height, and the notch is definitely bigger, giving it a mini-swallow tail. The tails rise as high as the tips, although they don't claim to be twin tips. Can't tell from the pics, but it looks like your tails are about the same as your tips. I guess with the plastic piece they can't be considered true twin tips even if they are the same height.
