New CP - Breaking in? Wilson Plat.

[JPaco54]

Tried on my new Wilson CP Platinum last night. First Hard Shell protector. Once I got it adjusted to fit snug I noticed that the side pads near the underarms were digging in and every time I raised my arm or arms the pad rubbed and it also lifted the CP upwards. Is this normal for this type of CP. Some have mentioned in this forum that it takes awhile to break in a hard shell protector. Will the pads soften up or should I cut the pads back? Overall it feels stiff and akward. I am 5"10 175 pounds. The CP is the 13.5" size. Thanks in advance for you input.
