I've used 4 versions of Hamskea older through current and never had an issue with the arrow getting caught off center, and I've tested with Micro Diameter Arrows too. My guess is for someone to get an arrow off center like that, you'd have to draw the bow pretty damn torqued to one side. Only launcher issue I've had with them is the felt peeling off but I've had that on every other rest that uses it too.
Containment on a Hamskea is a non-issue. I've used them for tree stand hunting, but also Elk and Mule Deer where I'm spot and stalk hunting crawling through the sage, or chasing bugles over 15 miles a day. You get used to it, and if you're really anal it's easy to use a finger to stabilize the arrow. The fact that I've seen two different QADs on two different bows being shot by two different people fail the same way at the same time on an Elk hunt was a "Never Again" moment for me. The launcher wasn't letting down and dropping on the shot and was resulting in trying to shoot through the launcher arm - no bueno. Last thing I want is wondering if I'm going to have a failure that costs me an animal I've worked all year for.
If I wanted to try something that wasn't Hamskea, I'd probably be looking at AAE next.
