There has been some debate about the elevator balance weights in icing conditions. Ice (or other foreign matter) can build up in the balance weight notches, and cause them to bind up, effectively locking up your pitch control. Additionally, the thin BID strap over the balance weights has very little grip on the lead weights. If they experience any shock, the balance weights can slide out and jam the elevators.
The solution is the debate - many builders have argued (some strenuously) that no fix is necessary. However, the fix is extremely simple and appears to have minimal downside. It consists of two changes. The first is a layer of BID on the SIDES of the elevator balance weights. This serves to provide additional support to prevent the weights from sliding out of their straps, even if the straps lose their adhesion. The second is a small cup over the balance weight recess (large enough to allow for full travel). This may help prevent ice from building up inside the balance weight recess.
None of this converts the Cozy into a known-ice-capable aircraft. Indeed, if the cups DO fill with ice, I'll have exactly the same problem, only this time it will be harder to clear the ice out. But the small amount of additional protection seems worth the effort, and I've learned that ultimately, the pilot/owner must be the final arbiter of what goes into or onto his/her aircraft!
