I did review of my Aero P1 leg guards a while ago, you can read it here:

I don't know what is a top hat problem but the pads have _never_ gotten in the way of playing any kind of shot I play. In fact, they have been the least disruptive pads for stroke play of any kind. Here is why I prefer them:
- Agility - they are the lightest pads in the market for that size. I can run singles all day long
- Maneuverability - because pads wrap around and have a very thin profile, footwork becomes as easy as walking normally
- Protection - have them against Bola as well, no issues
- Maintenance - easy to clean
The only negative I have experienced is that you have to wear Aero made Strippers/thigh guard which compliments the pads. If you inside edge the ball or miss lot of balls, you need Aero Strippers. I don't wear the strippers but on two occasions this season, I inside-edged two in-swingers to my thighs, one nearly missed my knee cap (I got lucky there).
