I have the HW100kt and the AA 410 Classic. The HW hits what I point it at, easily, and for that reason seems sometimes if I'm not needed, if that makes sense. The AA is slightly more of a challenge and therefore I find it more rewarding.
At the end of the day, you need to get to a club or gunshop and try all three for yourself, as only you will know how comfortable or not you find them.
I assume your '1.tt' calibre is supposed to be .177?
