If I did mostly jibs, I wouldn't get the fun.kink. I'd stick with either the Airobic or the ET because they have the 'true twin' TBT with a wider flat center section.
I've got an Airobic and it's a great park board and it does decent on the rest of the mtn. Sometimes, it is definitely too soft, and it's not gona win any speed competitions...but when you're out of the park, if you just butter and dick around, it fits the bill nicely. That said, I hated the extruded base on the Airobic - but then again, I think extruded bases suck balls no matter what board they're on.
I don't know if I'd take the Airobic off a 40 footer though...
IIRC, they're making a special run of ET's this season that have sintruded base.
