A welled handle device comprising a base with a front and back end having a predetermined silhouette or outer contour, a plurality of open wells formed in the base, and a tool portion connected to the front end of the base. An RF pulse shape may be optimized according to a set of Bloch solutions defining a desired magnetization profile. Alternately, such surface features may have a hemispherical shape. The performance peer includes a plurality of modules for providing respective performance enhancing functions to minimize performance impact of latency of the network.
