For the last three days I've had meetings about 2 miles from my office. There was no parking at the meeting site so I had two choices - public transit or walking.
Because the weather was OK (Monday was a little iffy and I cheated and took public transit one way) I decided to walk.
I was carrying my x-230 (fits nicely in the Mac 13 Ristretto), an iPad, an ARC notebook and dumped my watch, two cell phones (with belt clips), pens, change and keys into the bag as well in order to speed my way into the meeting - so about 6lbs. I'm wearing a suit.
A while ago I had attached a standard strap to the Ristretto which was fine from/to the car and from the car to the office.
Day 1 - standard strap - about halfway there I'm thinking "let me put this on the other shoulder."
Day 2 - Red Oxx "Claw" (often compared to Absolute strap) - when I get to the meeting I'm thinking "much better than yesterday, but it clanked the whole way, looked out of place and scrunched up the suit jacket because it just won't slip at all."
Day 3 - Absolute strap - albout halfway there I'm thinking "did I leave the bag at the office?" and on the way back I checked again.
The standard strap is fine for very light loads (iPad, pocket book etc) but as soon as you add any weight - even a three pound computer - you start to notice the weight.
The Red Oxx is better than most other straps out there but it certainly isn't attractive, it makes noise and isn't good for suits.
The Absolute strap is the cat's meow. I never realized how good the strap was because I always carried fairly heavy loads in my TriStar/Aeronaut and they were always heavy - no strap can fix that.
Everybody - regardless of brand of bag carried - needs two absolute straps.
