I use a valve tap, connected to a holster mate and that stops all the kinks n snagging and all difficulties. However a univalve sounds a pain as you have to grab hose at base of your pole to tug on or off. I recently and i mean only last week got this and its even easier

Honestly Nathan, I think you would be surprised at how easy the Univalve is to use as well. Most people watching a WC whose using one would probably wonder how they are turning the water on and off. It's so quick, if you blink you'll miss it.
If it wasnt for trying a friends pole with this device on, i would still be vindicating the tap valve, lol as i have on other threads. But i soon changed my mind after trying it, tho personally i still use the holsters as it saves me looping near on 24ft of pole hose to next job. After trying this im ordering one for my spare pole that i use with backpack. I could try a univalve with that one, but there has also been many threads on here about the best pole hose to use with it etc etc. Yet i find with the gooseneck valve you dont have to worry about it, ever. Just a sligth turn of pole for flow on or flow off. It cant be any easier.
However, i know we all have our own techniques and favourites but thats whatbi like about this forum, you can get new ideas from each other.
I would say go tubeless with the univalve
Water control, no loop in hose, protected fittings they don't get damaged then leak
The blue Exceed hose is so durable I ditched the microbore totally and now use 100mtr of it, this makes the running out the hose so light
If people think the univalve is a game changer, couple it with the tubeless set up and it's another level
I have tried the Gardiner aqua tap. The first was so stiff it wouldn't operate and in true Alex fashion he offered me a refund if I returned it (it's still on my desktop somewhere) I ordered a second, probably to get free delivery, that was better but no where near as good as the univalve. I think it stresses the joints in operation when turning on upper windows
