One area that is easily overlooked when considering low instrument minums is the effect on the Cat A/PC1 performance. If you are making an approach to Cat 2 minimum then it is likely that you will need to reduce the speed considerably by the time you arrive at DA/DH; after all, most Cat A LDPs are at 100 ft or there abouts. However, a balked landing from a Cat approach allows for a descent down to 35 ft agl whilst accelerating to Vtoss, which is more than the ILS procedure would allow for.
On the other hand, keeping the speed up (even down at Vy which could easily be 80 kts) presents all sorts of problems when transitioning from the approach to the landing. This is one problem the fixed wing world do not have.
