Firstly the only thigh pads I have currently are in the photo above, all the others have been sold or passed on.
I have been using the GM original set in the nets so far (but haven't played a game in them yet) they are great.
the upside of the shamrock ones is that they do fit better the downside is that the are marginally thicker... both sets are good.
In comparison to the Hawk ones - the original hawk ones that I had in the very first post were, in my view better than the second Hawk set I got, both in terms of fit and performance. As you can see I have had to adjust the GM ones with extra velcro to help them fit better, but that is not a bit deal. I hold out high hopes for the shamrock ones. These are the large mens option.
