Hope I'm not speaking out of turn Davie but if you are leaning towards the Tiger 1200, take it from someone who's owned both it and the bike you currently have, it's a backwards step. There's some things about the trumpet I miss. Its triple engine is a real peach, makes power from low revs, has buttery smooth midrange grunt and howls addictively at high revs delivering imho more punch than the boxer higher up, but less punch lower down. It makes for a smooth A road mile muncher, effortless overtakes and I found suspension to better my GSA TE, and the screen was way better. It was also more comfortable for the pillion. That's where the good news ended for me. The reason I got rid was that I just couldn't look past its top heavy weight, the so-so brakes and front end dive. It was literally a right pain to manoeuvre off the bike or at slow speeds. It really does require a lot of man handling and strength. After almost dropping it several times and already suffering an arm injury, it was a breath of fresh air getting onto a GSA. The GSA as an all round package I think betters it and is much easier to handle. As for reliability, they're both similar with the trumpet really not that much better (they still suffer electrical glitches especially) and the finish on the engine casings tends to peel off after a few years all year round use.
