Hi, firstly, nice skiing! You are smooth in and out of the turns and to me it's not just about making the course it's about being silky around the turns (which clearly you are) this divice is designed for all boats as the pole is the same width. The E Z CAM is designed to be a correction tool, a divice to learn from and help you improve. The footage is about what you can expect, you will always get a margin of shake (it only does what the rope tells it too!) great footage and nice skiing dude. Small cameras work great also in the phone cradle. The iPhone 5 seems to react from engine static for some reason like when you first hit record (I've seen this on other ones too!) go-pro is a good divice as is iphone 4 and 5 for the mount and a good old fashioned camcorder works great too! Always pop some lube (hair conditioner etc) on the inside before use as it helps keep it friction free.
Unlike other mounts on the market, E Z Cam is designed to take most divices and fit all ski tow boats So you can jump ship onto your buddies and whistle his/her own choice of camera on and go for gold ;)
We don't say it's 100% perfect,we just say its the "BEST IN IT'S CLASS"
I have tried a mount with a slot each side, test were not as stable as e z cam. It's worth taking the extra few seconds to trail rope back out..
George has some new stock coming shortly
Kind regards, darren "e z cam"
