Hello all, I'm going to install a beaching bumper on my Stratos and wanted some feedback on which one to get. I know the Hamby's dealer install is probably the best but my boat is already over 20 years old, so I am looking to just do a self install. All three have a lifetime warranty, but Hamby's lite is most expensive, followed by Keel Shield, with Keel guard being least expensive. What has your experience been with either of the three products? Thanks!
