Very disappointed with the new style. I recently had to purchase new Contigo water bottles because I lost one of the old ones & the lid of another one broke (it lasted for a very long time). The new lids are very bulky/heavy. There is no longer a clip which I used all the time (women have to carry multiple items everywhere we go so being able to clip the water bottle to your purse was very helpful!) and the new straw set up does not work well. The previous straws were a hard plastic & all one piece which worked great. The new ones are a more flexible plastic that does not always stay inserted into the lid even when you push it in tightly. 
I really wish you had stayed with the previous design. You know the saying,  “If it ain’t broke, don’t fix it.”
