Initial Equipment Choice

I’m fairly confident this topic has come up before, but I haven’t located the specific answers I need…My main interest lies with the Holy Trainer 2 and the CB-6000. Having read numerous glowing reviews for both, I have a solid grasp on the sizes required, even if it isn’t perfect yet. I get that proper fit is crucial. Still, one worry remains: my testicles drop quite low—lower than average in my view. Will this cause issues with a ball trap setup? Can I simply lower the device and extract myself without trouble? I don’t want to throw money away on gear that won’t suit me…
