What cabs for Invader and Liberator

Hi!

I've been wanting to try out WGS for some time now and finally, after listening to all availabe samples and YT demos, came to a decision and ordered an Invader 50 and a Liberator 80 from one of the European dealers (Haar Guitars, NL). I should have them next week.

I have two separate 1x12 cabs for them:

1. A compact (20" x 16" x 11.5") closed back, DIY made of solid alder. I've bought it empty a few days ago and haven't heard how it sounds, the seller says it has a rather warm tone.

2. This one, which is open back (MDF) - http://www.palmer-germany.com/mi/en/Products/Guitar-Cabinets-1-x-12/CAB-112-V30-Guitar-Cabinet-1-x-12-with-Celestion-Vintage-30-8-Ohms-PCAB112V30.htm

Except it's a 25th Anniversary V30 and 16 ohms... sound just as bland and unexciting as most V30s out there :) I'll be selling that speaker as soon as the WGS arrive but might keep the cab for now, at least it looks sturdy and well made, MDF or not. I bought it on a bargain price when I was in dire need of a 1x12 cab.

My amp is a Blues Jr (1st gen) converted into a head with upgraded OT and tubes (2 x 6V6, 20W) and a few of the BillM mods. My favorite tones are slightly overdriven but still blackface-y, I'm trying to abstain from hi-gain stuff thought I still own an EH Metal Muff will play the occasional Megadeth riff :D

I was thinking of installing the Invader in the alder closed back and the Liberator would go to the open-back, do you think that's a good combination? Of course, I'll probably swap them after they're broken in to hear the differences but would like to get some opinions + suggestions for other WGS speakers I can try?

Thanks!
