Do neither. Save yourself a bundle of cash by buying some Army Surplus Camo gear and improving your field craft. A bit more care and some patience (setting up a hide or similar and being prepared to wait for hours) will mean that a 500mm lens should be adequate for most jobs (it definitely will with a 1.4x or 2x convertor)
Unless your taking pictures of Snow leapords or similar (did anyone see our planet on BBC?) ;-)
