  Composite Fermion approach using extensive and parallalized numerical
analysis has recently established a two-roton bound state as the lowest energy
long wavelength neutral excitation of FQHE for finite particle (N~30) system.
By focussing on the "oriented dipole" character of magneto roton, we model the
two roton problem and solve it variationally (analytically) to find a two-roton
bound state with binding energy which is in good agreement with the composite
fermion numerical results.
