I use an Ego-Mostly with the Mega Atty and Mega cart. The reg 510 Atty and carts just dont give the same taste and vapor as the Mega Atty. I just got some LR Atty's and all I can say is WOW-what a differance.,But I still have to fill the regular 510 carts to often. Now if someone made a LR Mega Atty for the Ego that would be awesome.
