Never found it that hard, you have to concentrate on the opening Reviei, and all flows well from there. I actually find the hardest part to lein at a normal pace, I am so used to going fast on Simchas Torah to speed everything along on the 8th, 9th, 10th time around.
yungerman1 – You remind me of a funny story, when I was a kid I once heard a baal korei mistakenly do the Taanis yud gimmel midos on Shabbos Chol HaMoed! You would be shocked how many people followed and said the yud gimmel middos out loud!
