I'e got a Hood Stowaway system on a 1979 Gulfstar 37. Works fine, but there are two areas you have to be careful with.
1. You need to keep a slight tension on the outhaul of the sail when rolling it back into the mast. Otherwise, you can get a slight wrinkle or lump of sail which can cause a jam when retracting. Not usually a problem, because you notice, roll it back out a little, and then start again.
2. a more serious issue is that you have to be standing in front of the mast during the rolling in and out as that is where the mechanism is. So you have to leave the cockpit, climb up on the cabin top and roll and unroll. Since I singlehand a lot, this is an issue I did not have on my previous 33hunter, that had in mast roller furling, but could be operated from the cockpit. If you are going to the expense of having roller furling, from the cockpit is safer and easier.
Also, parts for these older Hood systems may be difficult to get. I haven't needed any, but so far have only found one spot that people "tell me" I can get parts.
