You are trusting that each radial will be resonant on only one band
akin to a fan vertical antenna. What may happen, for instance, is that
the 40m radial may accept an appreciable amount of energy on 15m and
direct the 15m signal up at a high take-off-angle - less than optimal
for 15m operation. Other interactions are possible, e.g. 28MHz/4MHz=7,
18.14MHz/3.6MHz=5, etc. Any vertical radial resonant at 3/4WL, 5/4WL,
7/4WL, etc. will have a suboptimal effect on the take-off-angle.

I never considered this Cecil. Would you think it better to use a wire
trap dipole instead of the Hustler 4BTV
and hang it vertical in the tree ?

My experience with the Hustler 4BTV hasn't been good. Over two hamfest
I bought 4 of them, lucky for me I was only buying then for the tubing
and mount and paid around $10 each for them. I dont think any of them
had a trap that wasnt bad.

I have decided against the use of the Hustler 4BTV. I am going to buy a CB antenna for use on 17 through 10 meters, keep the feed line short, and use it with a tuner. I have been reading that several Hams are doing exactly this with the Antron 99 and Sirio Gain Master CB antennas, with decent results. I do plan on a self supporting tower one day, but this will get me on the air, until then.
