Top
Topside = awesome bit of kit .. can be a bit heavy unless you're minted enough for the carbon, still quite large. I was happy for the extra size/weight though as an offset for the cracking all-round quality.
AEGIS Squonk, good bit of kit, bottle replacement is fiddly, and the tab on the battery compartment can be loose on some and cause it to fall over some times when you put it down(I hear this is rare though)
Bottom
Hearing good things about the V2 Pulse bottom fill.
Can't think of any others..
