Nothing to do with the balance! The UL (UF too) has huge elevator power, so you always have enough to flare. Then its 1/Weight, some people add a tonne of unnecessary weight. 2/ Trimming, nose heavy or not you can trim it to not drop its nose and pick up energy.
Most people would balance gear down, some fuel in the main tanks...cause you will likely always land with some fuel!!
Balance is subjective, Anyone who has flown one of Stefan Volker's designs will know for most its nose heavy. The Boss of CARF is the opposite, he likes neutral, more tail heavy. These balance positions get you flying safely, then adjust to suit your thumb-brain requirements.
