I can speak for the low profile, IMO it just protects the leading edge of the hood. Drainage is not an issue. I installed it myself, plenty of videos out there. I also installed AVS Aeroskin on CRV and Accord as well. If the leading edge of your hood is vulnerable, not a pad idea to install one. I like way it looks on the PP and it's much cheaper than film but that's a debateable topic.
