I was in the same situation as you a couple of months ago, and thought 1050 speed triple.
I test ride a 06 model, and was left a little unimpressed tbh. It's supposed to be the best of both worlds, torque of a twin, screams of a 4. Erm...... Not exactly. More like the worst of both world's, and not my cuppa.
Got back on my gen II and thought 'this is miles better'. (grandma :-* )
I rode a few different machines, the mt-09 included, and loved it but couldn't justify it for my needs (16-20k/annum), the z1000 too, loved the looks, but it's cost again for me.
I settled for my two bike line up, a carb'd R1 with a comfort kit for playing, and my Thundercat for commuting (60mpg, comfy, nimble
)
Have you thought about 2 bikes? In reality it only costs me an extra £200/year for insurance/tax/MOT.
Why compromise when you can have both?
