A quick question about engine commonality

[yoshininja]

So I'm currently in BW1, playing in South Korea. I've been using the bog standard IL-114's with the Klimov engines for my domestic routes.
However, I just opened a base at Pusan which is the only airport apart from Icheon which has a worthwhile short-range international market.

My question is, would it be worth it to buy five, maybe six 114's with the PW engines to serve these routes or would the increased maintenance costs make it a pointless venture?
I'm the only show in town for the domestic/not Seoul Incheon market in Korea and I expect it to stay that way since the only other airline in the country is focusing there.

Opinions would be welcome.

Engine commonality is usually a very small item compared to the overall costs.

agreed with our revered administrator : engine commonality costs are rounding errors.
