Another thing that I find is the therapeutic aspect of handlaunch. I find that after just a few minutes of tossing and searching, I feel better. It is a great stress reducer.
There's one more thing I can think of that HLGs do that you just can't do with any other type of airplane: get aloft and stay aloft by the lightest of slope lift. In some fields or other flying areas, ones that have a rise or just the slightest place for slope lift to start, you can get a handlaunch to 'slope' soar. I've flown a HLG for hours or longer by sloping off the front edge of some short cypress trees at the end of a field near where I used to live. I've also used the slope lift from the front of a large house. Sometimes while flying thermals, you'll get a bit of slope lift at the same time. Hey, lift is lift; just take advantage of it whenever you can.
When building, use just enough glue to hold things together, not the whole bottle because 'it seemed to be the right amount' for maximum strength. Note that glue joints with an excessive amount of adhesive can actually make a structure weaker due to the added stress areas, i.e. the place where the joint is is strong, but just beyond the joint, the structure will tend to break. It is sometimes better to have a joint 'give a bit' in order to redistribute the stress load. When covering the HLG, choose the lightest covering you can find, but don't compromise in the wrong areas. For example, MicaFilm clear is regarded as the lightest, strong mylar covering available for aircraft. It won't be that light, however, if applied over large sheeted areas because you need to use an adhesive (Balsarite) under all of the MicaFilm in order to get it to stick to the wood. MicaFilm is more suited for covering open 'stick' structures as there isn't much wood to paint Balsarite on.
