i tried the VIPER. i am only 6/1 210 but ole sproul likes room.the top of viper was just tight for me .the bar out front was not out front far enough.

so i tried the 180 MAX.that sucker has room on the top and rounded bar gives me lots of knee clearance out front .but floor is still size of viper.this year they went to TITAN floor.

that was good idea. i had to get foot rest for my 180 max as my size 11 boots were hanging on ends.
i found out in life i have to get everything 1 size bigger than i take forme to be comfortable and that includes my treestands.
