Tweaking a R/G Beatz deck...

There are many iterations of the R/G Beatz deck. Some focus on manlands and cursed scroll, going for aggro. Others include BM and Null rod, hoping that key disruption gives them a long enough window. Mine falls into the latter. Here's the list - comments to follow

MANA (25)
4 Taiga
4 Wooded Foothills
5 Forests - I like to get BM on the table quick
3 Mountains
4 Wastelands
1 Stripmine
1 Mox Ruby
1 Mox Emerald
1 Black Lotus
1 Mana Crypt

Beatz
4 Kird Ape
4 River Boa
4 Troll Ascetic - sometimes I mix 2 CotH, they work well with a T1 crypt
3 Rancor - not as consistent as cursed scroll, but that won't fit in this deck

Utility
3 Lavamancers
4 Mox Monkeys -
4 Lightning Bolts
4 Incinerates - considering some F/I, I like the speed and damage of Incinerate

Disruption
3 Blood Moon - neuters opposing CoW's
2 Null Rod

SB - varies considerably, currently:
3 REB
3 Pyroblasts
3 Tormod's Crypt
1 Blood moon
1 Null Rod
3 Artifact Mutation
1 Rack and Ruin

The concern I have about going the disruption route is that against some decks - I can have upwards of 5 dead cards main deck with no real solution in the board, just the lesser of two evils. At this point, I'm thinking about dropping the Kird Apes in favor of Mogg Fanatics. My thinking is that the gobbo can kill some key cards - welders, fish creatures - and even possibly on a really good day, an early dryad. The matchups that generate dead cards for me are mostly other beatz decks. I can't justify dedicating SB slots to these decks in my mind. The one card that comes to mind is Maze of Ith, mainly because I can work that in against other decks as well - TNT, GAT. Any suggestions for improving the main deck or SB for the NE meta will definitely be listened to...
