I use the Accugroove Wedgie, small, light, and has a clear flat response. I got rid of my other cabs after hearing the Accugroove.  But Keith has a good point, if you already have a cab that you like, try to come up with a way to direct the sound at your head.  I once made a light weight angled cab stand out of PVC pipe and a foam wedge, it worked well.

I have played through a Fearless & it had tons of bottom end, but it did not have the range or flat response the AccuGrooves do.
 
Before I got my Wedgie I used a Fender Rumble combo on a tilt back stand, so you might try that if you are happy with your existing cabinet. I made a platform to sit on top of the Rumble that had wood strips on top so I could sit my rack on it tilted back without it sliding off.
 


 
 
Now with my Wedgie I use a work platform I got from Home Depot. It is the perfect size & height for my racks & it folds up flat for easy transportation. http://www.homedepot.com/p/Husky-X-Workhorse-Workbench-17185155/202021304
 


 
 
The AccuGrooves are expensive, but very much worth the price if you can afford them! I will never buy another brand.

Victor Wooten has a simple solution to angling the cabs.  You could easily build a wooden flat cart and screw a two-by-four on the front edge to create the same effect.
 

That's definitely simple  My next gig I'm going to try angling a spare 2 by 10 cabinet I have and just see. I'm continuing to look for somethign even smaller so it won't affect anyone else on stage, and my cabs will still aim at the audience. Might end up building something, but probably not too soon.

Just to add some closure to the thread, I ended up getting a small Phil Jones Bass combo amp - two 5 speakers - that'll sit on top of my rig and angle up towards my head. I'll play out with it this weekend, but in rehearsal it's been nice to have the definition of the notes and not just the rumble. Also, a cute little living room or vocal rehearsal amp! http://philjonesbass.com/store/bass/bass-cub-bg-100/

Glad you got what you wanted! Enjoy!
