Disclosure: I work in a shop, selling North.
I have had a Select 138 the last 2 seasons, so both 2014, and 2015. Prior to that I have had a team series (2013), couple of Jaime pro (2012 and 2011)and before that boards from naish, cabrinha, airush and litewave. I'm old, late 40's, like free riding with mates and kite mostly in the standard perth chop. I like a good blend of comfort and speed and find that the select has the right blend of flex tips so it eats up chop and stiffness through the centre to keep you planing, for me!
We sold heaps of selects this year to guys just like me. Yes it is expensive, are there cheaper options, yes the north x ride has a pretty similar performance for about $500 less, but it's a bit heavier and not made of carbon

.
I have tried the monk and like everyone says it's super comfy, but a has a very soft flex pattern, and I found sucked a little power from the kite. The nearest board we have to the monk is probably the best Admiral.
The old rule still applies demo demo demo.
We don't have a select in demo but if you are up at kitestock ask nicely and I might let you try mine
