Best bottle gun?

This Altaros reg is apparently made for the Wolverine B:

Are these the ones that spoil the appearance of bottle guns?

I saw that the Huma reg doesn't fit in the Wolverine B. I don't really know much about aftermarket regulators. I've been curious how well these reg brands work compared to the factory regs in my current air guns.
 
I keep looking at the RAW guns but I can't find enough data on how they perform as a 22 with a shorter barrel. Plus I'm too impatient to wait for them to build it for me.

I like guns to be ready to ship as soon as I decide I want them. Three months is more than enough time for me to lose interest.

There is a lot to like about the RAW guns though. They definately deserve consideration for the top spot of bottle guns. 
 
The RAW is a solidly engineered gun with precision manufacturing, topped off with assembly and tuning by the number one expert on RAW airguns in the world. I recently bought a .22 HM1000 wit the standard stock in red laminate. It is not flashy. It is more purpose driven.
Unfortunately, due to an extremely lousy winter here in Boise I have not had a chance to shoot the gun outside. I have never heard anyone complain about RAW's accuracy, though.
Shooting a short string with JSB 18.13 Diablos I get the following numbers: 852, 850, 850, 847, 847 for 29 fpe. It is 44 3/4" long and weighs 9 3/4 lbs with an old Weaver T10 steel scope. It looks pretty much like the .30 HM1000x above except the fore end of the receiver, where the front ring is mounted, is about 3/4" shorter. The difference is due to the larger pre chamber on the x, making the x suitable for larger calibres/ energies. I especially like the standard stock as above for comfort and control. The X is $275. more, though. One thing about the Raw is the ease of swapping barrels.
Although long, the RAW is well balanced . handles well, and feels lighter than it really is.
I will be using my .22, and another .25 RAW I have for sniping ground squirrels over grass/ sage. So I don't really mind a longer gun. Last year I was using a Cricket BP, but I just couldn't warm up to it. RAWs are starting to show up on the used market at attractive discounts. Call RAW about a shorter barrel. I'm sure they can offer some advice.
I don't think you'll find the RAW as pretty as the Daystate or the FX. It has a certain industrial quality to it.
