Which oversize tank?

I have an 09 WR450F and am looking for an oversize tank, 3 to 3.3 gallon.  I've looked at Clark, Acerbis and IMS and am looking for feedback on what I should use or avoid.  I have an FMF megabomb header and from the pictures it looks like some of the tanks may touch it.  

 

I don't like the look of natural, black or blue are OK and the radiator shrouds have to fit.  And do they use the stock cap or their own?   

I cannot attest for the use on an 09 WR450 but I have purchased and used at least 4 IMS tanks. I have had zero fitment or reliability issues with them. I also know people who have bought Clark tanks and no problems with them either. I cannot speak to the Acerbis.

IMS looks the best, has the lowest 'ball hump', and are plentiful used and new.

You have to change to YZ shrouds if you want a perfect cosmetic fit, or modify you stock shrouds.

What capacity is that one?  Can you post a pic of the right side?  I need to know if it will clear the megabomb header.  

3.2 gal.

 

This tank will not come close to any header.

I have the Acerbis 3.1 (or was it 3.3?).  One nice thing about this tank is that it connects to radiator where the lower shrouds normally do.  The tank is very solid and acts as a radiator brace.  I never bent a radiator while I had my tank on, but when I went back to stock and added the EE rad braces I bent a radiator on the second ride.  The Acerbis keeps nearly the same width at the knees.  Also, no problems with the bomb header.
