The local "expert" has recommended that I switch to a rotary hook (drop-in bobbin) machine to better suit my needs.
He says that he works with parachute material a bit and has specifically chosen to use rotary machines for that and the projects are going to be almost identical to what I work on (tents, packs, tarps, etc...1oz nylon and 1.3oz silnylon...plus heavy duty webbing at times)
Anyway, I do believe him to an extent because he actually has some stuff to back up his claims that rotary hook makes a better quality stitch without puckering.
...any input or experience the community has on this?
Is he just trying to make a buck or is it really worth it (likely in the $150-200 range compared to my $100 Necchi 3101)
