Pyramid Irish Bouzouki Strings

O.K. so I've just received a lovely new Irish Bouzouki and wanted some spare strings. I haven't even decided on my preferred tuning yet! Reading the instrument reviews shows that some players prefer octave strings for the G and D (as in this set), while others prefer to double up on wound G and D pairs. I simply ordered 2 sets! Now I have the option either way and if I choose to double up with wound strings, there will be a pair of thinner strings to try in a different position. Wikipedia references show a common tuning as G-D-A-D. This set G-D-A-E, I thought was octave mandolin. They sound good anyway and there is a lot of experimentation and controversy still about tuning!
