PG, best maps!

[Juiceman]

If you are looking for a double sided tape try a Removable Repositionable Tape, such as 3M 9415 or an equivalent brand.  It has high tack on one side and low tack on the other.  Might be a bit expensive per roll, would test out before you use it on your maps just to be on the safe side, would also double check the high adhesive side on your table, the high tack side might not be as easy or clean removal as the lower tack side.
 
Personally I have not used it on my PG maps, have known other gamers in the past who have used it.
