Thanks for the reply John.
I'll go with just lace. That's what my last piece was and i didn't have any issue with the bond on that. I don't think i'll be allowing anyone's hands to go near my hair for a long time till i'm 1000% confident and comfortable myself.
Also, i don't wish to go any longer than 3 or 4 days between de/reattachment, so i'm sure just lace will do me fine.

Thanks for your help
