Glasser Carbon Graphite Violin Bow 4/4

I have used this bow for a half year now as my beginner bow, and while it looks very nice and doesnt sound bad in any way it is a bit on the light side. My teacher recommended me to stop using it as soon as possible..
I suppose it could be usefull in cases you need a light jumpy bow but i will be following his advice.
One problem i noticed myself is that the screw on the end does not stick very well, and i would normally have to tighten the hairs once or twice in a practice session (1-2 hours) which does get very tedious.
