No experience with the Hot Launch, but I have several older offset drivers, mostly component, that I no longer use if you wish to try an offset driver inexpensively - could send you head only or as shafted for cost of shipping.
LMK if interested and I can tell you what I have. I do have an older Tour Edge Bazooka QLS (on a steel shaft).
I guess I don't have anything as high as 15° but the 10.5° Snake Eyes Viper Ti 462D launches pretty high.
The more I type the less likely I think you may be interested. 😁
