Might need a 12" speaker cab. Prefer 8 ohms and weight under 35 lbs.

Was thinking of this: http://www.sweetwater.com/store/detail/SupChampX2SC How would this be?

Any ideas or suggestions?

Also, considering having a cab made and would then want speakers recommendations. Initially, thinking of an Eminence 12" Texas Heat speaker.

Music style is slide blues and blues/rock, not high gain and primarily with a lap steel and sometimes slide guitar.

Thanks so much for any and all advice.
