i use an E1 cocker and I love it, i've played with Angels before and i prefer the way my gun feels, like everyone has stated, it is really down to personal preference. Cockers can be a little tempermental but so can every gun out there. In many ways i prefer fixing my cocker to trying to sort out closed bolt markers. With a cocker, u learn what each individual part does - its all mechanical and logical. That way i find it easy to sort out any problems that arise. I was playing a tournament with my teammates Angel and it went down about 30 seconds off the break and i just couldnt work out what the hell was wrong with it, theres no visible working parts u can check or whatever, with a cocker you look at it and if its an obvious fault u can rectify it easily. One thing i will say about cockers is that dialling them up and down can be a bitch unless youve got a REX Dialler installed which makes it much easier. But yeah, try both, go with what you like, if you lived anywhere near me i'd say come down and try mine out. Just dont listen solely to all these Cocker haters
When you've got them working theyre beautiful.
