3 use Vlocity's,3 use Rotor's.I have run a rotor on every marker I've had mate without problems, also some of my teammates use the rotors, one of them on his ego 09 without any problems.
Think you just got unlucky with your last rotor mate.
The majority love theirs and wouldn't swap it for anything else. But if you do have your heart set on using something else there is the Empire Prophecy, which has had mixed reveiws from people i know who bought one.
Or you could go down the Halo or Reloader B route bud, both good hoppers and half the price of the rotor or prophecy.
With the current BPS limit being where it is, almost all hoppers will be capable of keeping up with you marker, just comes down to ease of use and what you prefer.
If i remember correctly, certain members of our team have had nothing but trouble with the vlocity's in the past.3 use Vlocity's,3 use Rotor's.
I use a Vlocity with a hyperdrive chip,no problems,fast feeding,reliable,not as good on batteries,but the chip improves battery life.
And now very reasonably priced.
I will try a Rotor one day..perhaps,if the Vlocity naff's up....if.
Depends who's playing,of the base team of 6 we have 3 of each..as I said I've had no issues...nor Chris...If i remember correctly, certain members of our team have had nothing but trouble with the vlocity's in the past.
And only 2 use them, the other 3 use rotors. We are a 5 man team remember Tiffer.
Big Smithy, you could always try the new Invert Halo too hopper mate, LIPS have just got them in....
