  In supersymmetric models with radiatively-driven naturalness and light
higgsinos, the top squarks may lie in the 0.5- 3TeV range and thus only a
fraction of natural parameter space is accessible to LHC searches. We outline
the range of top squark and lightest SUSY particle masses preferred by
electroweak naturalness in the standard parameter space plane. We note that the
branching fraction for b-> s\gamma decay favors top squarks much heavier than
500 GeV. Such a range of top-squark mass values is in contrast to previous
expectations where m(stop)<500 GeV had been considered natural. In radiative
natural SUSY, top squarks decay roughly equally via t1-> bW1 and Z_{1,2} where
W1 and Z_{1,2} are higgsino-like electroweak-inos. Thus, top squark pair
production should yield all of t\bar{t}+\eslt, t\bar{b}+\eslt, b\bar{t}+\eslt
and b\bar{b}+\eslt signatures at comparable rates. We propose that future LHC
top squark searches take place within a semi-simplified model which corresponds
more closely to expectations from theory.
