I think Larry must have gone out filming, but he is definitely the one to answer this one for sure.
I cannot tell you specifically about the Wide Glide, but I can talk some about single hooks and lures.
Lets talk walk the dog lures for a moment.
I have found that single hooks up front do not work that well, period. On most walk the dog lures, the balance does not change that much when going from a normal treble to a heavy single, so that is a non-issue. What I have observed is that all too often the fish takes the whole lure in the mouth and the single up front lays down against the side, preventing a good hook-up. Changing to a single hook up front cost me lots of fish.
On the other hand, a single hook on the back is perfect. You have much easier releases, less fish damage, and as you mentioned, a stronger hook for the same weight.
I have experimented with a double hook up front with the hook eye and lure eye turned so that the double hooks are turned out when the hook is pushed toward the lure. It works, most of the time, if you can rotate the lure hook connection.
Please understand that I prefer single barbless hooks for a lot of lures, mostly because I prefer to release fish rather then clean them.
But, I prefer to catch fish most of all, so if a treble hook is best, that is what I use.
I have no doubt that you can find single hooks that will weight close enough to the factory treble hooks, but, consider what I have said. Most importantly, see if others respond with their experience in this matter. And when Larry gets back, he can straighten us out.
