Pick One: Fx Impact X - Fx Wildcat MkII - Fx Dreamline

Is go with the dreamline.
Reason is I bought an iimpact just because of the adjustability. Now the have the same thing pretty much that you can customize to your liking. 
if the dreamline holds up to the fx accuracy I think it will be the best bang for your buck you can get. 
I don't see anything the the dreamline is lacking plus not having a bottle looks better I think.
 
The impact is one that I already own it’s a good all around rifle with many barrel options and calibers as well as adjustability,the wildcat is a nice one also but not available in 30 caliber. The Dreamliner is a convertible system but it’s priced as more of a starter gun system you can build on I haven’t read any reviews on it yet and until it’s independently looked at I wouldn’t recomend unless the cheaper price is all you want to spend. I would pick the Impact over the wildcat as there is more adjustability but if you plan on just one barrel setup it probably wouldn’t matter as much. If you could only have 1 gun get the Impact for sure 
 
Can I say, I don't know? I'm saving for either an Impact or Crown. However, now that the Dreamline has the adjustments found on those two guns, what is one of the main features I'm after, a Dreamline might fit my needs and leave enough money for a compressor and other toys.

Why not the Wildcat? the adjustments is the only reason. I figure by the time I outfit a Dreamline to be like a Wildcat, it'll cost over the $1000 mark and probably close to a Wildcat, so they are about neutral price wise. If I could easily adjust the Wildcat transfer port and hammer spring, I'd go with it in a heartbeat.

This summer I'll buy something new, but probably wait to see what FX does to their overall lineup. The Dreamline could replace the T12, Streamline, some of the Royale's, gladiator, Ranchero, Cyclone, maybe Bobcat. It won't replace the really high end Impact or Crown, yet. The semi-auto guns will remain, and the arrow guns, for now until FX Brings out an arrow barrel for the Dreamline. then all bets are off. FX could consolidate the less popular lines all into the Dreamline for a killer platform.
