Solving Large Overdetermined Systems

My equation system consists (at the moment - by taking all linear combinations, the cubics surely can be pruned too) of 18 quadratics and 360 cubics in 15 variables. Solve[] is out of question, for NSolve[] it's still too large (not mentioning that there are some 1-parametric solutions), so I turned to FindRoot[] - one found "random" solution would already be very revealing. But alas, FindRoot[] needs #eq=#var. Bummer. (Of course I can take 15 random equations and plug the solution back in, but the probability of 378 zeroes is zero...) Any other idea what I could try? -- Hauke Reddmann <:-EX8 fc3a501 at uni-hamburg.de Er-a svo gott sem gott kveða öl alda sonum, því að færra veit er fleira drekkur síns til geðs gumi.
