James,
You might check with Richard at Aviattic my old friend. He was kind enough to supply me with PE rib tapes for my SE-5 conversion project earlier. These Aviattic rib tapes I've used really are a major improvement for the Roden wings. I'll post photos on my Conversion thread soon,so you can see the results for yourself.
Highest Regards,
Gregory Jouette
MERRY CHRISTMAS TO YOU AND YOURS
