OG Skytrak Spin Numbers

I’ll start by saying that it is entirely likely that I need a reality check, so let me have it if that is the case.

I am running an OG Skytrak with an outdoor hitting net (see photo). The first photo is with a Sim2 8-iron and the 2nd photo is with a Kirkland 60 deg. I am using Vice Pro balls.

I posted the 60 deg shot to show that I indeed can get backspin on the ball and that my Skytrak can pick it up. The problem I’m having is I can’t get any decent backspin on my 8-iron, or any of my irons in general. PW-LW is not an issue, I get decent stopping power out of those.

I have tried all the tips for Skytrak. Draw a thick line on the ball, use a tee, check the height of the Skytrak, adjust lighting, move the ball 1-2 inches behind the laser, etc. Nothing is getting me optimal spin numbers. I’m aware that Sim2 is a GI iron, so an 8-iron is really the loft of a 7-iron, so mixed with a Vice Pro ball, I shouldn’t be expecting 8000 spin. But I am consistently in the mid-high 4000s and this 5000+ was one of the few I was able to muster today.

Is this what I should be expecting? I’m a 19hcp, so I am by no means “good.” I’ll be the first to say that the problem is likely me, I just want to make sure it is me and not something I can be fixing with the setup.
