When I bought my first and only should pads I preferred the fit of the 2 piece in my Supreme One.8 pads. I've been searching for slimmer, less bulky pads like the crazy lights or apx2 and I noticed that most new pads are all one piece. Not sure how to explain the feeling but I like how the 2 piece is tucked under the shoulder caps and moves with you rather than lifting the cap when move your arm.
Do you guys have a preference or are there other features that you look for in particular with respect to shoulder pads?
