I'm about to pull the trigger on a navy suit in the $600-700 range. I'm down to either one of Suit Supply's top "Suit Up" line or a Hickey suit on sale at Bluefly and my Nordstrom's for $699. I'm favoring the Hickey (tried it on and verified nice fit) but am concerned about the "Loro Piana Tasmanian Super 150's wool". The interwebs suggests that S150s might not be terribly durable but do you think that's a minor concern when the wool is from this kind of quality source?

I’m no fabric expert, but my understanding is that higher Super number means nicer feel but less durability, regardless of the wool quality.
