The man Chen Fei, also known to us as GZK, has sent a parcel of technical rubbery goodness to Slingshot world again to try out for issue SIX . Do you recall seeing his videos about weird and creative ways to use tubes?
Known as COCKTAIL tubes, there are two main kinds. One is the Y-cocktail, where you use the same tube but create a differential pull-strength along the tube bandset’s length by partial doubling-up. The other one is when you get a narrower tube slid inside another tube. In the video below, he clearly states that the Y-cocktail tube system is faster than single tube, faster than all-doubled tube and even… faster than flat band! Quite a claim to make and one I want to check in the Tweaky Tech issue SIX! So yes, the Chronograph is coming out. (Such a shame that the maker went out of business.. their F1 lasts too long, so repeat sales never became a thing!)
The very slings used above to show the speed difference between regular and Y shaped ‘cocktails’ in the GZK video have been sent to me! We can examine, prod, poke and CHRONY these! And we are going to… should be interesting.

We also have GZK “BRA” pouches to test, a lot of the high quality GZK anti-cold green tube and a new ball insertion device as well as the stick-it-all-up-themsleves thingamajigger for sliding a soft rubbery thing up a snug rubbery hole.
