Thank you guys one more time.
I think that Rowniwn and Camzace are both right. It really depends on person and goals. Staying in 180s is very comprotable place to be and you have much less headache about swings etc. But its always possible to learn and play same time other things as well and maybe you can find something better for yourself.
Personally, im not sure what kind of plans i have and im gonna think about it more seriously in December.
