I just wanted know the opinions of my fellow magis on this....

the hundy 500 is a similar effect as slow burn but it is 10X better i suggest that u get that.

if you really want to choose between those two i would say get both of them. they are doen differently and both have great effects. i woulde recc. that if you are going to get slow burn that you look into hundy 500. the gimmick is the exact same but the handling is easier and less angle sensative than slow burn. so your choices shoudl maybe be hundy 500 or visibill and then i still say get both. i have all three and i think they are going to be great. i havent practiced much with them but i have watche dthe dvds over and over and i cant wait to get the time to practice. college schedule is kinda hectic.

if you have your heart set on one of the two tricks you listed and not hundy, i would say go with visibill. i really liek it and richard sanders is a great teacher.

hoep this helps you out a little bit and good luck with, hopefully, you r next purchase

check the visi bill demo. its easy as that.
