I own a Sony NEX-5R, which I use heavily for low-light shooting, with a Gorillapod. The Gorillapod is rated for 1kg, and the camera is 466gm. When I press the shutter button, I get camera shake, which I've learnt to work around by using a 2-second timer. I later read on photo-SE that that's not enough, and that I should use a 10-second timer, so I do that now.

Should I upgrade to a heavier Gorillapod, like the SLR zoom (rated for 3kg, and designed for SLRs) or the Focus (rated for 5kg, and designed for full-frame SLRs)? Would that let me take photos more conveniently, and with no or shorter timers, like 2s instead of 10? Or is there likely to be only a marginal difference?
