Thanks - I am looking forward to this review when it comes out.
I've had to cancel my planned trip to the BRP for this year, meaning I have no idea when I'll get back out for a long ride to use the blades again, so in the interest of wrapping this up here's where I have finally settled regarding the PSR Highway Blades: I don't love them, but I like them well enough to keep them.
On a scale of 10, 1 being awful, 5 neutral, and 10 ideal, I'd give them a 10 in build quality, about a 7 in ease of use FOR ME, and 6 in overall benefit to me. This is NOT a knock on the product, it's my subjective assessment of how much I feel I personally gain from having them, versus not having them. Here's how I arrived at those values.
They're well made and relatively easy to install. Once the mounting bolts are torqued to about 10 lb-ft they do not rotate on the tip-over bars. I don't care a fig about the over-vs-under the tip over bars installation aesthetic; in fact right now I don't even have the plastic tip over guard covers installed.
I can deploy them from fully retracted by reaching down and flicking them partway open with my hands, more easily than I can by using my feet alone. This is less than entirely convenient (or safe) and discourages me from using them at a whim, but doesn't make them untenable. If I remember, I do it before getting rolling.
Once they're partway open my feet can do the rest. And I can partially retract them by hooking my toes on the fronts of the blades and giving a gentle pull.
They position my feet and legs fairly comfortably (I have a 31" inseam) but as mentioned elsewhere they also put my calves in contact with that edge on the fairing. Boots with thicker soles might help with that.
I'm notoriously inflexible in the joints, and after a while on the blades my hips start to stiffen up. Then it's time to go back to the regular foot pegs.
Hope that helps you in your decision-making process. Happy riding to you, no matter what you decide.
