I have used my spin twin a LOT and love it. I use the two person shelter as a decadent solo shelter (cheating? maybe) THis is a PERFECT shelter! I cannot praise it enough! Simple and tidy!!!
THe tie outs work fine, - never had an issue. A little bit of silicone glue a head of time may help.
THe SIL-twin is slightly less expensive, and slightly heavier.
Crinkle noise soved with a snugley pitched tarp.
THe Gossamer Gear design little pul tighteners are really simple and work wonderfully.
I do NOT have the kind with the velcro door.
I am 6'1'' tall, and the length is perfect, the width would be tight with two people, but not impossible.
I use a head-net to sleep if it's buggy, and never use a "real" tent.
