Hi John,
I always recommend to newbies to start with a French lace unit with poly on the back and sides. French lace and SFS are made of the same translucent material only French is stronger. It's a little more forgiving for newbies who are 'getting the hang' of attaching and removing. Once you get a little more experienced wit the handling a system you can try other bases. Either Super Tape or Walker No Shine tape is an excellent choice. Both are very strong. Tapes and glues are a bit of a 'trial and error' thing in that you need to find out what works best for you. Liqui-Tape is a great strong bond and Ultra Hold glue is the strongest.
Regards,
John
