i have 9" sps legs sitting around...half is solid and the other half is perforated lines....once i cut them for a cake size i need...is the left over area that is the perforated lines section able to be reused also as a leg for sps for future cakes or is that section not as stury on its own?...

Sorry to see that nobody responded today... I'll say this--they are certainly stronger than using straws!

Find "leah_s" (just do a member search up at the top purple part of this page)and private message her, she know all the ins and outs of sps and I'm sure could give you the right answer.
