Replying to Marker or Salomon? +K

So I'm thinking of getting new bindings and I think the griffons are my best choice.

Here are my options:
(Prices in AUD)

Marker Griffon Bindings $349.99 (might be able to get them for $329.95)
Marker Squire Bindings $259.99

Salomon Sth2 13 Wtr Bindings $349.00
Salomon Warden 13 Mnc Bindings $349.00

I am 60 kg (132 lb), roughly 170 cm (5.6 feet)
I normally have it at 6 and I ride park half the time and all mtn, the other half (nothing steep)

I want a binding that is relatively light but durable. Since I am only on a din of 6, would the squires be good enough? Are the salomons an overkill? Marker is probably more favourable as more shops stock replacement parts.

I am getting the K2 domains so would the markers work better because they are under the same umbrella corporation?

So what is your past experience/opinion NS on these bindings?

I want them to last a few years as well...

Cheers, +k
