i'm trying to decide which type of wing bands to buy. there are two that seem a lot alike to me but their applicators are different and have a $15 cost difference. i like the Zip bands because they are silver, which seems less noticeable, but the applicator cost $15 more than the Jiffy applicator. the Jiffy bands claim to be the most popular wing band in use, but they are $1 more/hundred and only come in brass or colors. is there really a big difference in these two? is there a better option?
