Personally I use the stock XL280 now that I run 3x UAC5's and 2x Mlas. Used to use just the UAC5's and XL300, but didn't perform as well.
Looking at Smurfy, if you're using regular AC5's, I'd suggest you go with the XL320 if you have it lying about. Just messing around with it, my build ended up with 270 rounds of AC5 ammo and half a ton left over. Naturally, you'd probably use that for armour. 270 rounds is
plenty. The only time I've ever wished for more (I have 210 on my UAC Ilya) was when myself and a lancemate got completely ignored on a flank, enabling us to unleash hell for near 2 mins of constant fire with impunity.
The circumstances I describe above are incredibly rare. The extra speed of the XL320 should enable you to reposition faster, thus enabling you to unleash the dakka.

If you can stomach learning to use the Gauss with the charge mechanic this will work well.
Muromets, I modded the build for the XL320 you now own.
Good luck with the 3 cataphracts, they are all great mechs!
Only two? Weak.

Clearly, this is a joke build. That, while liable to get you killed in short order, is hilariously fun and I heartily recommend you try it. As long as you're not a uber-seriousface player who must win at all costs, that is.
