[TowerTalk] Crank-ups

[Alan NV8A]

My XYL is urging me to consider a crank-up (and possibly a tilt-over 
crank-up) to avoid the necessity of climbing the thing, and also partly 
for a more neighbor-friendly installation.

1. Does anybody have any experience or opinions of the Heights aluminum 
towers? -- in addition to the reviews on eham.net.

2. If a crank-up lattice tower gets iced up, is it pretty much stuck at 
its current height until the thaw sets in?
