wah i also want the curah 52" leh.Wanted to buy the Alaska curah 52" de, but after testing it at the shop, i hoot the point one instead.
Curah max 6th speed is around point one 4th speed, in term of spread i don't feel any difference. Curah 1 year onsite warranty, point one 2 years. Point one installation is $10 cheaper.
Overall, point one is $35 to $85 cheaper.
considering this and point one vortex/cyclone
may i know which PO fan did u get?
