0* vs 40* squeegee?

Why does everyone rave about the 0* but never a word about the 40*? I am going to order a Unger swivel loc but cant decide which one, Im tired of struggling pulling angled windows and trying to pull ledges. Thanks for the help guys

I did order a back flip which should help a little with ledges, also ordered a angle adaptor. Going to move up to a 30ft poll from a 18ft I use now, I better start working out if I am going to work that thing all day!

get both
