@BillConnerFASTC Let's quibble. Bottom roller is ideally supported by the drop once it's reached its lower end of travel. I proffer the bottom roller is only supported by its ends while the drop is at its high trim and while it's being rolled either up or down.
@BillConnerFASTC Pardon my ignorance but what's a "biard"?Empirically, they don't sag when up. I believe the load is spread out throughout travel. I used to specify manual bottom roller projection screens, and the roller remained very straight.
Test it with a strip of fabric, stapled to a biard and a dowel. Roll up, pull on ends of dowel without allowing it to unroll. I think the fabric will not yield and apply pressure along the dowel.

One space I work in had a similar problem. I convinced them to install a track (or horizontal fly system as I like to call it) which works pretty well. Of course, you need to add a pipe in the bottom which adds an extra step to deploying it but it's much easier than taking it down and putting it up. We do have a protective wrap for it and so far, it's stayed fairly clean. I've often dreamed about something like this: http://www.rosebrand.com/subcategory758/dmx-roll-drum.aspx which may be an option for you depending on how wide your drop is. I guess it does bring up the debate about whether or not DMX control should be used in a situation like this but I hope that doesn't hijack this thread!
I'll also second @TheaterEd's desire to see how a curved roll drop works.
I'll give a thumbs up to this. Have never had an enjoyable olio experience.

We had a 60 year old bass player fall into ours a couple weeks ago.@Lightitup Shooting every kid that comes within a hundred feet of it is the first thing that comes to mind.
The cleaner, better, and more blemish-free the cyc' the more it invites people with dirty, sticky fingers plus open beverage containers.
Toodleoo!

@Jay Ashworth If you'd flown your bass player out to 48' and his double bass to 58', you'dve still had 2' for over travel and minimized your problems; keep in mind AF of M rules for oxygen masks, seat belts, diapers and emergency escape slides /n shutes. The wrinkles may have hung out of your bass player by now as well. @derekleffew and @TimMc Care to comment??We had a 60 year old bass player fall into ours a couple weeks ago.
And we *do* have a full loft to fly it into, so we were understandably pissed.
Most of it has hung out by now.
I've got a similar issue on my hands. We have a 43' fly, but our cyc and scrim are both 29' high. Unfortunately, due to having only 19 linesets, we don't have the option to trip anything. Ideally we would just want to shorten both of them just enough to match where our borders sit, around 20'. I haven't found many good resources on properly doing this, and I can't imagine it would be possible to hem the scrim in house. Does anyone here have any experience in soft good alterations?
