With the annual UK subscription for all the charts that an IMC rating holder can use legally at IRO €500 (€400 for the renewal) it would seem that you are working very hard to save the cost of 2 or maybe 3 hours flying and with an electronic subscription soon to be available at IRO €180 your argument rather falls apart.
Remember that this is the private flying forum - for many here 2 or 3 hours is a significant amount of their annual flying!
