I prefer the tall screen, and I've moved from one bike to the next for 4 R3Ts.
I use the tall screen year round. It is a quiet cockpit, it is warm in winter, and it is bug free in summer.
This means that I always have a stock windscreen to store until it's time to trade the bike, and then the stock screen is reinstalled.
I just lay the stock screen on a shelf in my shop. I don't put stuff on top of it, but aside from that, I don't do anything special.
The stock screens are always as good as new when I'm ready for them. More impressively, the tall screen takes a lickin' and keeps on tickin'. I have no incentive to buy a new tall one. It's still optically excellent, even after all the bug strikes over many summers.
