That depends on the particular LBT. There are several nose configurations, and some are better balanced overall for use at different velocity levels.
Here are some comparison figures if I remember them correctly: A classic Keith for a 44 has a .270" meplat, an LBT LFN has a .300" meplat, and an LBT WFN has a .340" meplat.
The LFN is usually a good balance between aerodynamics, weight distribution, and "smack" that works over a range of load levels.
