Overall, it's a good quality product just like everything else Line makes. I'm not sure if the grab tab is right for me but it's worth giving it a shot. Worse comes to worst you could easily unscrew the grab tab and still have an awesome pair of poles.
I'll be completely honest, I was a little skeptical of the whole grab tab thing. I've learnt to grab with two fingers and hold on to the pole with my thumb, pinky and ring finger. It was hard to gauge whether or not I like the grab tab because I had to change the way I ski. However, I lent my poles to my brother and he liked them. He always wears mittens so he is used to grabbing with his whole hand.
I've always skied with either cheap kids poles or none at all so these are definitely the nicest poles I've ever skied with. It's also the first time that I actually lock up my poles with my skis. The grip isn't uni-directional like most ski poles so I don't go all OCD when my pole is slightly twisted. It sounds stupid but I love that about them. The strap is really nice and comfortable too.
There are a few things that bother me about these poles. I've found that the optimal height for a ski pole for me is about the length of a cane so I can keep the poles short and push off easily with the palm of my hand. This proved to be annoying with the grab tab. Another thing that bugs me is that the Line graphic got cut off when I cut my poles down. They're such awesome looking poles so I was a little heartbroken. I thought it would be important to note that the yellow grab tab and red pole baskets happen to go with my NS jacket. It worries me that people will think I did on purpose to match.
