I have had the same morrants ultralites for the past 5 or 6 seasons and they are brilliant. They are far lighter and less bulky than traditional pads and are certainly no less flexible. The lack of side wings is no issues as I have never been hit there (why would you be hit on the side of the leg?). The only issue with the morrants is that everything sticks to them, grass cuttings, fluff etc, though this is a minor drawback.
I would certainly give moulded 2 strap pads a go, especially if you are a little older and slower and would benefit from a lighter weigh and the same quality of protection.
