No one in their right mind will trade a cocker for an ego, so try n be realistic about it.. the ego is everything the timmy was 2 years ago but with none of the flaws!
They are so straight out the box there is practically nothing you can do to them them that will even get a drop of performance from them - most Ups for them are either harder replacements like a stainless steel ram cap so you wont thread your alluminium one, Bolts
, Mounts with guages, and frames/triggers that to be fair most feel are more a down grade than an upgrade.
Rest is purely cosmetic.......
Hope that helps
