Yesterday I played Forest Hills in Holiday FL, which is a 9 hole ball golf course with an 18 hole DG course. It is along the Anclote River and has ponds everywhere. There is only one hole without water danger, and many holes have water on multiple sides of the basket/tee. It's not too far from the coast, so if you go too far on one of the river holes and want to retrieve your disc from the water, you could be attacked by either a gator or a bull shark (or maybe they play tug of war with you?). So having a disc you can trust 100% to go out over the water and come back could save your life...
So I figured it was time to break out the Stiletto...and boy did it deliver. I can't tell you how ridiculous and fun it was to play with this disc out in the open. I should have lost it...I had one shot where I yanked it with my ugly FH far out over water with enough torque, angle, and OAT to keep it going straight away from the basket for a long time...It hit the water right as it was transitioning from turned over back to flat and it jumped off the water, not once, but twice. The second jump got it up on the bank about 80' left of the basket, but it wasn't done yet. It skizzled all the way up the bank and toward the basket until I had about a 40' putt, which I hit. It was perhaps the most ridiculous birdie I've ever carded.
I don't have a huge arm, but I have decent snap and can throw flat and with varying degrees of anhyzer pretty well. For me, the Stiletto was super useful on that open and danger laden course. I DID NOT have to learn the Stiletto, it was intuitive. I hit the pole on a 320' hyzer where I had to pull it low and out wide to the right and let it get around a bunch of stuff and then move almost laterally toward the basket. I love this disc.
The only thing I can compare it to is the Nuke OS, but it flies with more glide and curvier lines in the air...almost perfect parabolas, where the Nuke OS is completely glideless and turns at almost 90 degree angles (I've only thrown the early runs of the OS). It is also a little deeper in the hand than the OS, which makes it feel much better to me both BH and FH.
If you can throw 400' and don't throw with a permanent hyzer lean, you can probably find a use for the Stiletto, even if it's primarily in the open or wind. I can see a lot of people using this for their overstable utility disc, though I did not try and OH shots. It's in my bag for an official testing period, that I can say for sure.
