Tree Following January 2017 - You Got a Friend

Way back in the day when I purchased my quince tree it said very clearly on the label that it was self-fertilising.  I believed this and took it at its word.  Now it may well be a self-fertilising tree, but so far the quincelets are not developing to maturity and this is a disappointment.  Every year the tree gets a year older and a year more mature.  Who knows, this may be the year that it is mature enough to enable a quince to fully develop, who knows.
So far this winter I have opened up more light for the quince tree by pruning neighbouring trees in an attempt to give it more help.  I have also bought it a friend, yes I now have two quince trees in the garden.  The original tree is 'Vranja' and I have bought a Oblonga 'Champion' to keep it company.  This tree is also labelled as self fertilising and apparently (believe it or not) is ready to fruit.  Yes the seller made the bold claim it is ready to fruit.
I am therefore hoping that might two self-fertilising trees will encourage each other to self fertilise or indeed fertilise each other and produce a quince.
Is it cheating to introduce a second tree into tree following - probably
Am I going to drive you all twice as crazy by having two quince trees disappoint me with a lack of quinces - very likely.
How much do I care on a scale of 1 to 10..... I might need to avoid answering that.
