if you liked the zowie ec series, i think you should go for the EC1-A
u're in usa, u have this 1st world privilege to buy anything online and send back the ones u don't like so just do it
dont take it as a rule but for alot of people using a mouse that is way smaller than their lead to better aim (especially if low sens) and in length you should go for something around 60% of your hand length, so if the ec2 doesnt give you cramps or hurt your hand i dont think if its a good idea to change it
anyway ec series,g402 (or the wiresless one) and deathadder are similar to yours
Ec2b deathadder, rival 310
Steelseries Sensei RAW/Sensei 310
Zowie fk1+ imo if you like ambidextrous.
Or Deathadder Elite (I have it and I love it)
Krypton 500, best 30 euro mouse for big hands
Razer Deathadder Elite, best around !
