It's bad form to post on this site just to get your count up. It's even worse form (although honest) to come out and say you're posting just to get your count up.
What do you consider a "weird" buffer? Guessing from the stt2 moniker, you have a Spikes powdered tungsten buffer in your AR which is a nonstandard (and thus arguably "weird") buffer. H, H2 and A5H2 buffers, weird or not, are very effective, especially the A5H2.
One item you'll want to add to your SBA3 is the Split Fix
