Not a bad idea in a case like this.
Don't service the octo this year.
Replace it with an Atomic octo or SS1 next year when you have the Atomic serviced.
Then both will be on the same every other year/300 dives service schedule after that.
Sounds like a good idea. Atomic Octo is not a cheap one (I think its 250) but I think it would be a good long term investment.
Thanks
