Yes, gents I realize that seeing is the key to a blissful night of high resolution viewing. However those nights are rare in the case of Jupiter in particular for some reason.
I agree that a large dob will do nothing if the optics are below par. At present it seems to be a lottery at best and this is at the risk of the buyer.
I guess that that one night in 5 years is quite possibly the ratio to finally seeing what you hope to see on that massive gas giant.
I have owned a large newtonian during the Hayleys comet of 86 (?) mania and it did indeed show great DSO's, but for planetary it was a total abomination

!!!!
It seems a shame that going up in aperture withe the various brands available at present is o.k. for the faint fuzzies, but not a guarantee for good planetary viewing also
