That's about 35 minutes too much time. :)
Those look pretty cool. Two things, though... I only regrip my clubs once per year, so the extra 35 minutes doesn't mean much in terms of my decision in what grips feel good to me.
Also (and I know this contradicts my previous statement), I have three girls (two teenagers and a 10 yr old). Maybe I WANT the extra 35 minutes in the garage and away from any drama that may be going on in the house ;).
