Mara...I've never done the Jamaica Zipline Adventure Tour...quite frankly, I didn't even know they were still around, but had heard good things about their zipline years ago. I've done the Zipline with Chukka Tours in Lethe...fun & professional.

Since you're considering a falls visit, have you thought of visiting YS Falls that offers ziplining right on their property. Maybe you're set on Mayfield though...which of course is more rustic but fabulous.
