the quilt on my bed has wool batting...and is the quilt that stays even in the summer time. the wool batt washes up wonderfully, makes the quilt 'lofty' soft and cozy but it breaths. we do not (sweat) at night, it is warm but not *suffocating*
i love working with the wool batts (dream wool) and if i could afford it would put it in all of my quilts. because it is more on the higher-price side only special quilts get it :thumbup:
my vote is for the wool, you won't be disappointed.
