what fx should I buy

I have a bobcat, Impact, and a boss (of course it .30 not .25cal). I love them all.

The Bobcat is heavy, 80shoot/ fill. It nice on target shooting. If I go on the hunt, I will need the tripod. Even though with the heavy weight, but the feel of the gun make it become the gun to go all the time. 

The Impact is more complicated and fun gun, a lot of shoot per fill, too. It definitely lighter than the Bobcat. They are both accurated for me. You can chance the caliber in the future if you want to add more to your collection.

A lots of members here are really happy with their Royal 500 as well. 
I hope it help you a little bit

I was going to point you towards the Royale but, then I read about the hunting aspect. It is a long rifle at 46.5" which makes it seem heavier than it is and could be challenging in the woods. Of your 3 choices the Bobcat seems like it might be the best choice. Decent size, a bit heavy, extra magazines can be carried in the stock. The Impact is a tuners delight but, if you don't want to tune at all, then it's hard to justify that aspect. The Impact is ~3/4 of a lb lighter than the Bobcat. So, if weight is a major concern, that might steer you towards the Impact. A bottle generally will give you more consistent shots per fill. The Impact has a lot going for it. 
I generally try not to do this but... I'd like to toss in 2 other FX rifles, for you to consider, that might fit your needs...
FX Wildcat - It's very light, accurate, and comfortable to shoot. You'll get ~40 consistent shots per fill. You can pick up a magazine holder for it on Ebay that will allow you to hold 3 loaded spares, or you can reload the magazine while it's in the rifle. It's very quick and ergonomic to cycle to the next round for a quick follow up shot. Mine has become my go-to rifle for pest control and some competitions. 
FX Streamline - It is based off the Royale but, is almost 2 lbs lighter and almost 10" shorter stock. I'd recommend adding a couple sections ($25 ea) to the moderator for sound so, let's call it 41-42". Regulated, low price, traditional styling. I can only speculate (mine's a .22) ~40 consistent shots per fill in .25. Turn a wheel for large pellet speed adjustments. Fine tuning can also be performed pretty easily. 
With all FX rifles, the Synthetic stock is the way to go if you want light weight. 
Sorry to throw 2 more in the mix for you but, I felt compelled to do so. The biggest downfall to the ones I mentioned would probably be shot count. 
Happy shopping!

Mine is Bobcat MK2, it comes with standard regulator. 2 powers adjusted!!!
Like Tom said, the wildcat will be lighter, but won't have the power wheel adjuster. It is really nice gun as well...
You will be hook either way with FX, I have number 4 coming is the Steamline .25...
if u are in no rush then, FX lover will chime in. I'm sure u will find the one fit u. 
Good luck!!!

Have you considered a trip to Phoenix to look atthem? That might be worth a plane ticket. I need to see some of these side my side as well as Daystate.

That idea aside, I would look at Streamline for light weight and field use.

I have had all the fx rifles and believe me you can't go wrong choosing anyone! My personal opinion is the impact hands down if you want to go fx if not the cricket is a strong runner up! 

FYI, there is a .25 Bobcat in the AoA used section right now $1050
(as well as a Royale 500) 

Sean,
I have been shooting my Impact for about 6 months now and I absolutely LOVE it!!!!!!!!!!!!!!! I have ran about 2000 pellets through it and it has operated flawlessly. If you choose the Impact just make sure you read the small manual 3 times and understand what you can and can not do!! Misuse of this high tech rifle will damage certain components. For every negative comment you read about an Impact there are thousands of owners who are super happy with this gun. It really is a Ferrari and if you use it like a Ford and do not understand the in and outs of its basic workings you will have a failure.

Have you considered the verminator mk11, not the extreme version. It's a pretty lightweight and compact hunting rifle, that's available in both .25 and .30

I looked at every air rifle FX makes before I settled on the .25 Wildcat.

Now, the wait is on. I'm looking forward to getting it.

I think you'll enjoy that just fine bltefft.I put a sling on mine(bobcat) it hangs nice for walking,shoulders well.Thinking about a pocket swivel in the side of my 500 stock.for a field gun.never will be a brush gun,

+ 1 FX Bobcat Mkll better shot count than Wildcat.
