If you are running stacks and get scared of the screen not being enough protection, I have an old trick for you.
Back in the day, and mostly on brit bikes.....racers would use pantyhose (on the bike

)
Find a pair that the wife/GF either doesnt know about or is throwing away and tell her you need them...this alone should be fun, but wait there is more
Cut enough to sandwich between the stack and the carb throat and let the stack hold it in place. I have never tried it, but it sounds like it would work.
