Wow,
I feel like a nic hog!
I started with 24--then bought some 30 and 36.
Use them all daily pretty much non stop.
Used Marl reds (then 100's when they came out) for almost 48 years.
Guess thats why i need the high nic.
No problems with it to date ,
No head aches
No sleep problems
Most of all--NO tar-chems-and stink any more
