Hi Charlie,
Welcome to the forum !
Well, the Spirit 2M is a very good choice for a beginner !
But if I may, I will choose something with ailerons, like the Spirit Elite (if you want to stay with the Spirit) or an Easyglider (not wood, but foam).
Ailerons will gives you more responses from the glider, and if you fly mostly at the slope, that will help you a lot in the turbulences, and to stay on the slope.
A rudder/elevator glider is really fine, but sometimes, the slow reactions (especially when the wind is coming from the back of the glider) can put you into trouble...
And flying with ailerons straight away, will prepare you better for the next stage !
I hope that will answer part of your questions, but don't hesitate to ask more if you need it !
