Replying to Salomon pro models, to buy or not to buy

So I just tried on some of last years salomon pro models tonight and I'm deciding whether to buy. I think they might be the boots for me since I have a pretty narrow foot and the boots i currently own are the green 1080s. So I just dont know if i wanna spend 400 bucks plus i kinda wanna try on the diablo magnesiums so i was wondering if anyone knows how they pro models feel compared to the tecnicas. to buy or not to buy whats the verdict?
