Iown and have tuned both.
For me the drop zone would work when the TT would not. I guess it drops faster after providing enough arrow guidence to send the arrow off correctly. So in a word- ittuneseasier.

The TT is quieter with my moles skin & weather stripping job.

I set up the TT yesterday on my Stalker and do believe it now quieter than my Patriot[8D]. Granted the arrows are arcing towards the target instead of blazing there.

They are both quality rest, but I think the TT is a little more durable. Those slots and springs on the dropzone look like a place for dirt and grime to get into and gum up.

Can't go wrong with either one IMHO, but your shooting a Patriot so I'd say DROPZONE for you. It would work on my Pat when the TT would not.
