Ease of use and versatility are also better with fixed clamps. There are some string patterns you won't be able to do with flying clamps, like JET. People who use flying clamps often resort to double pulls, which loses tension. If you have a fixed clamp machine and some extra money, you might want to invest in a flying clamp in addition to your fixed clamps because it will allow you to do more patterns, like ATW. I really think fixed clamps are one of the most important features for job quality.
Wow! Thanks for all the useful info! in that case I can't imagine not choosing the fixed clamps. Thanks for the help.
