I liked that wire spider of Alan's. But if someone is concerned with 
spider spikes, why bother with a spider at all? I made a 16" dob and 
had a a piece of Starphire glass cut and used it as protective front 
plate and secondary holder. If I recall the glass was rated at 92% 
transperant in the visible range and had zero affect visually on deep 
sky objects.
