Just swapped out some blades on the sevr 1.5. I'll say its a bit of a pain to do that with them. May attempt to resharpen the blades I replaced to see if I can beat factory sharpness. Jury still out for me on them. They do fly well.

KS mature buck ran about 70 yards and tipped over. Didn't exit though and only hit ribs. Only about a 14 yard shot and a pretty heavy arrow setup. Seemed odd.
