yah pro hurricane tour full-bed is quite tough on the arm.. tried on my apdc prev. arm wrecker... with hybrid is much much more comfortable.. good thing abt pro hurricane tour... keeps tension quite alright...

most polys maintain tension very well, and the string rarely moves.
the downside is, ur arm gonna hate it. xD
now I'm totally into multi... Love the feel. Don't mind adjusting the displaced string bed from time to time.
