I recently replaced the webbing compression straps on my blast with spectra cord (see below). This saves about an ounce and lets me compress the pack much further. Can anyone see a problem in doing so (extra abrasion, snagging etc)?
The 3rd and 4th pic shows shows a system I was trialling using two rings to compress it and keep it in place (suggested by Evan from Terra Rosa Gear). The last pic shows my lame attempt at replicating golite's compaktor system.
