The prices are decent and it runs very well in my engines (OS,Enya,Magnum,Webra,ST,ASP). The S&W is used by many of our club members with good results, just not my first choice.
This will likely be the case. Omega only has 17% oil content. The lower the oil content, the higher the power potential (given the same nitro content). Most S&W blends have 20%. It's not uncommon to find pylon racers who run as little as 12-15% oil. Problem is as you decrease the oil content, the likelihood of catasrophic failure if running lean goes up exponentially. For this reason, I never fly with any glow fuel that doesn't have at least 20% oil content.
