Broker fees for micro-lots in energy futures

Curious if anyone has found a sweet spot for broker fees when trading micro-lots in energy futures ($CL_F, $NG_F)? I'm running some scaled-in strategies and the commissions, even on micros, are really adding up. It's making the entry cost a bit prohibitive for smaller accounts trying to manage risk effectively with the granularity of micros.

Are there any brokers that are particularly competitive on per-contract fees for these smaller sizes, or is it mostly just a function of volume that dictates better rates? Trying to figure out if my current setup is the best I can do or if there's a better infrastructure play for this specific strategy.
