I have had the honour of trying most of the top notch hoppers(paid for I may add).
Usually resorted back to Eggs,but finaly I've settled with a Vlocity and the upgrade Hyperdrive chip.
Found with Halo's and Pulses that they have feed issue when the marker is lent over on it's side during the course of gameplay.
This is what I found from personal use.
The Vlocity and the Eggs do not suffer from this due to the positioning of the feedneck in relation to the body.
If I didn't get on with the Vlocity I guarantee I would be back with the Eggs.
Torques fast,easy to clean.... but damned annoying,the constant whiring
.
In my opinion (or what I would use) Vlocity(upgraded chip;**** on batteries otherwise) or the Eggs(very cheap now;3 comes with the upgraded board and will keep up with a ramping EGO)...nothing else,and I have tried them all,I'm not repeating what I've heard...
